The Apprentice star Donald Trump is a grandfather again.

Donald Trump Jr. and his wife Vanessa have welcomed their second child, OK! Weekly reported Wednesday.

Trump Jr. and Vanessa -- who married in November 2005 -- welcomed their first child in May 2007, a daughter they named Kai Madison.

"[Vanessa] wants five [kids]. I might try to negotiate for a little bit lower," Trump Jr. had previously joked to OK!. "I figured I'd have some leverage after number one, but about two days after, she's like 'Okay, I could do that again.'"

Trump Jr., his sister Ivanka and their father will all serve as judges on The Celebrity Apprentice's second season, which premieres Sunday, March 1 at 9PM ET/PT on NBC.
