Mark Wahlberg Rhea Durham Welcome Baby No. 4 Margaret Grace

Marky Mark is a dad — again. Nineties rapper-turned-screen star Mark Wahlberg is celebrating the birth of his fourth child with wife Rhea Durham.

Rhea gave birth a healthy baby girl named Margaret Grace at Cedars-Sinai Medical Center in Los Angeles Monday afternoon, a hospital source blabbed to Star Magazine this morning.

“Mark was in the delivery room with Rhea. And he cheered her on all the way.”

Margaret joins older siblings Ella, six, Michael, four, and Brendan, 16 months. Mark and Rhea married in August after eight years of dating.
