Actor Mark Wahlberg is about to become a father for the second time with model girlfriend Rhea Durham, to a son who's due in March. "My dad called me Mike since I was a kid. So in honor of my dad, I think we’re going to name him Michael," Wahlberg told PEOPLE exclusively at a party for the Mark Wahlberg Youth Foundation Golf Outing at the JET nightclub at the Mirage hotel in Las Vegas on Friday.
Wahlberg, 34, who's one of nine children (including former New Kids on the Block singer Donnie, 36), has a 2-year-old daughter Ella Rae, with Durham, 27. Does he see any more children in his future? "I don't feel a need to outdo my dad," he says. "I have friends my age who are already grandfathers. I waited for the right time."
The actor, who's also the executive producer of the hit HBO show Entourage, will star alongside Leonardo DiCaprio, Matt Damon, Jack Nicholson and Alec Baldwin in the Martin Scorsese-directed crime thriller The Departed, due out next summer.
