The actor and wife Rhea Durham welcomed daughter Grace Margaret on Monday
Baby makes six for Mark Wahlberg and Rhea Durham, who welcomed a daughter on Monday, a source confirms to PEOPLE.
Grace Margaret Wahlberg joins siblings Brendan, 16 months, Michael, 3 ½, and Ella, 6.
The Lovely Bones actor, 38, confirmed the pregnancy in October, announcing that Durham was expecting a girl.
Will the brood continue to grow now that Grace has arrived? That’s up to his model wife, Wahlberg says.
“My wife is allowed to pick the magic number … as many as she wants to have.”
