Xavier Alexander Wahlberg is the firstborn of entertainer Donnie Wahlberg and realtor Kimberly Fey.
Despite having a stellar dad, Xavier prefers to stay away from the limelight and asks his dad not to mention his name on shows. However, Donnie reveals that his eldest son has inherited his interest in music and is a member of a hardcore metal band.
A curious fact: Xavier is very close with his father and they can talk about everything.
