Xavier Wahlberg, searched online as Xavier Alexander Wahlberg, is the elder son of Donnie Wahlberg, the New Kids on the Block singer and Blue Bloods actor, and his former wife Kimberly Fey. He is the nephew of Mark Wahlberg, not his son, a mix-up that appears on several websites. Reported to have been born in March 1993, he is an adult who is described as a musician and who has kept out of the spotlight. This article sets out the facts that reliable sources record, flags the middle name that cannot be confirmed, and describes the family and career context that readers searching for his name usually want.

Who Is Xavier Wahlberg?
Xavier is the older of Donnie Wahlberg’s two sons, according to a Yahoo Entertainment report titled about the actor’s two children. It gives his birth as March 1993 and his younger brother Elijah’s as August 2001, and it names their mother as Donnie’s ex-wife Kimberly Fey. Wikipedia’s entry on Donnie confirms two sons with Fey but does not name them.
One oddity is worth flagging. The reported birth date precedes Donnie’s August 1999 marriage to Fey, and the sources reviewed do not reconcile the two. This article reports both facts as stated and does not speculate about the timeline.
The same report describes Xavier as a vocalist and bassist in the Los Angeles metal band Upon Stone and says he does not use social media.
A Note on the Name
The keyword Xavier Alexander Wahlberg contains a middle name that appears only on content-farm pages. Reliable sources give the name as Xavier, and no mainstream source supports Alexander. This article therefore uses Xavier Wahlberg and treats the middle name as unverified.
Not Mark Wahlberg’s Son
Several websites describe Xavier as a son of Mark Wahlberg. That is incorrect. Mark is Donnie’s younger brother, which makes Xavier his nephew. Mark’s own children are named in reference works and do not include Xavier. Pages that merge the two households are mistaken.
Donnie Wahlberg: A Brief Background
To understand Xavier’s connection to public attention, it helps to know a little about his father. Donnie Wahlberg was born on August 17, 1969, in Dorchester, Boston, and rose to fame with New Kids on the Block before becoming an actor, while his younger brother Mark Wahlberg became a film star.
A Family From Dorchester
The Wahlberg family is one of the largest in American entertainment, with nine children raised in Dorchester. Several of the siblings have worked in film, television, and food. Donnie’s early fame with a boy band and Mark’s later career as a rapper turned actor are well-known chapters of the family’s story.
Xavier belongs to the next generation, and his documented connections are to his father, his mother, his brother, and his uncle.
A Large and Famous Family
The Wahlberg family tree is wide, which is one reason searches for individual members often return confused results.
Why People Search for Xavier Wahlberg
Interest in Xavier Wahlberg typically arises among fans of New Kids on the Block and Blue Bloods who are curious about the family of a performer with such a lasting following. Searches usually aim to confirm how many children Donnie has, what they do, and whether the Wahlberg surname links them to Mark. The reliable answers are that Donnie has two sons, that Xavier is the elder, and that he is not Mark’s son.
Donnie Wahlberg’s Career
Donnie Wahlberg co-founded New Kids on the Block in the 1980s, and the group became one of the best-selling boy bands of its era. He turned to acting with a role in The Sixth Sense in 1999 and appeared in the miniseries Band of Brothers in 2001 and in the Saw films. From 2010 to 2024 he starred in Blue Bloods, and a spin-off, Boston Blue, followed in 2025.
He also helped produce the reality series Wahlburgers, which earned Emmy nominations in 2014 and 2015. That body of work explains the steady interest in his family.
Family Life and Remarriage
Donnie married Kimberly Fey in 1999, and the marriage ended with a divorce filing in 2008. He married the actress and author Jenny McCarthy on August 31, 2014. These dates are included to place Xavier’s parents in sequence, since some websites confuse the order of the relationships.
Donnie has said in interviews that he does not speak about Xavier on television, which is a clear signal of the family’s preference for privacy.
Respecting a Private Adult
Xavier Wahlberg has not sought a public career in entertainment, and being the son of a well-known performer does not make him a public figure. Responsible writing about him acknowledges his parentage and his reported musical interests, and avoids guesses about his home, relationships, or finances.
Distinguishing Verified Facts From Content-Mill Speculation
Because the Wahlberg name is so famous, numerous lower-quality websites have published pages about Xavier Alexander Wahlberg that invent a net worth, a career, and an unrelated parentage. Reliable sources do not support those claims. Readers should treat any detailed profile of him found on such sites with strong skepticism and rely on the narrow set of facts presented here.
What the Record Shows
The reliable record shows that Xavier is the elder son of Donnie Wahlberg and Kimberly Fey and a nephew of Mark Wahlberg. It does not show a confirmed middle name or any details of his private life, and this article does not invent them.
New Kids on the Block and a Pop Phenomenon
New Kids on the Block formed in Boston in 1984 and rose to worldwide fame in the late 1980s with hits such as “Hangin’ Tough” and “You Got It (The Right Stuff).” The group sold tens of millions of records and remains active in reunion form. Their success gave Donnie a platform that later supported his move into acting.
For a son born in the 1990s, that history was part of the family backdrop, though the details of how Xavier experienced it are private.
Why Short Profiles Can Be the Most Honest
A short, accurate profile is often more useful than a long speculative one. When a person is not a public figure, there may not be enough reliable information to support a full biography, and pretending otherwise misleads readers.
Mark Wahlberg and the Next Generation
Mark Wahlberg became a leading film actor through Boogie Nights, The Departed, and The Fighter, and he has a family of his own with several children. His success has sometimes led readers to assume that any young Wahlberg belongs to his household. In fact, the family includes many cousins, nieces, and nephews, and Xavier is one of them.
Keeping the branches of the family tree straight is the simplest way to avoid the common error of attributing him to Mark.
Blue Bloods and a Long Television Run
Donnie Wahlberg’s role as Detective Danny Reagan on Blue Bloods ran for fourteen years and made him a fixture of network television. The series followed a multigenerational family of New York police officers, and its Sunday dinner scenes became a signature. A spin-off, Boston Blue, brought the actor back to a character set in his home city.
The long run of the show meant a father with a steady and visible career throughout much of his sons’ adult years.
Music as a Family Thread
Donnie’s musical career with New Kids on the Block was followed by solo recordings and reunion tours. A son who plays in a metal band is working in a different genre, but the shared interest in music is a thread worth noting. Reports describe the band as based in Los Angeles, and this article does not describe its recordings or performances, which the sources do not detail.
Reading Family Trees Carefully
Wahlberg family coverage often mixes up siblings, spouses, and children. A careful reader checks the generation of each person named, and prefers sources that state the relationship directly. In this case, a Yahoo report identifies Xavier as Donnie’s son, and Wikipedia confirms the two sons without naming them.
Elijah and the Wahlberg Brothers
Xavier’s younger brother, Elijah, was born in August 2001, and the two grew up as sons of a performer who balanced music, television, and family. Elijah is also an adult now, and he is mentioned here only because the reliable source names him. Both brothers have stayed largely out of public coverage.
Jenny McCarthy and the Blended Family
Donnie’s marriage to Jenny McCarthy in 2014 created a blended family that includes her son from an earlier relationship. McCarthy has spoken publicly about family life, and Donnie has appeared with her on television. Those public moments concern the couple, and they do not extend to documenting Donnie’s adult sons.
A Note on Sources
The principal source for Xavier is one Yahoo Entertainment article, supported by Wikipedia’s confirmation that Donnie has two sons. That is enough for his name and parentage, but not for anything more, and a careful reader should treat additional detail with caution.
Conclusion
Xavier Wahlberg’s story, as far as it can be reliably told, is defined by his place as the elder son of Donnie Wahlberg and Kimberly Fey, the nephew of Mark Wahlberg, and a musician who keeps a private life. The verified record is short, and it reflects that choice.
His story is a reminder that fame belongs to the person who earned it, not to every relative, and that careful writing respects that boundary.
