Current actor and ex-rapper Mark Wahlberg and Rhea Durham, his fiancée of four(4) years, are expecting their third child. 

Says a friend, "Mark is thrilled to be having another baby. He is an amazing dad, and his two children are his world. He always used to joke about wanting at least a dozen kids, but it looks like he wasn't joking after all."

The couple have 4-year-old daughter Ella Rae, and a 2-year-old-son, Michael.

Man, they've been engaged for 4 years? Glad to see they aren't rushing into anything.
