Last month I had a fact or fiction about whether or not Mark Wahlberg and his wife, Rhea Durham, were expecting another baby. This one I can now label fact.

"I'm having another girl," Mark Wahlberg told PEOPLE at GQ's The Gentleman's Ball at New York's Edison Ballroom on Wednesday. "So I'll have two girls and two boys."

Well, that works out well! Are Mark and Rhea looking to go for an even half dozen?

"I'm the youngest of nine, and my dad has a few others. No, four is enough," he said. "We were all raised with a lot of love. But we didn't get the kind of attention I think that we all needed. My parents had to provide to put food on the table. My mission in life is to raise my kids right. With all the success I've had in the world, if I fail at that, my life means nothing."

However, Mark is willing to defer to Rhea in making the final decision.

"My wife is allowed to pick the magic number … as many as she wants to have," he said. "What I want to do is I want to raise my kids right I want to give them the world. But I also want them to appreciate it."

Mark's brother, Jim, suspects there may be more children to come.

"He's good to go! He ain’t stoppin'," said the sibling. "He's got beautiful kids."

I guess no one from People thought to ask Rhea?
