Actor Mark Wahlberg: "Baby Due Around the Third of September"

Mark wahlberg n fiancee Rhea Durham is due to give birth to their third child, a boy, "around the third of September," he revealed to Usmagazine.com at Comic-Con in San Diego Thursday.

Though the longtime couple already have a 4-year-old daughter, Ella, and a 2-year-old son, Michael, Wahlberg only proposed to Durham recently.

"We continue to grow in our relationship, and we have a much better chance of succeeding and staying together now," the star of The Happening explained to Us.

"I was not prepared to be married, no matter who it was when I was 20 or 30," he said. "Committing to making it work and all the other things that go into building a solid foundation is where I'm at now."

Wahlberg also told Us how he balances work and family.

"My family travels with me when I work most of the time or I go back and forth on the weekends," he said. "I've been pretty consistent about just making phone calls in the morning and then chasing the kids around in the afternoon."


And while Wahlberg and Durham are thrilled about the expansion of their family, daughter Ella "was extremely disappointed when she found out that we were having a boy she wanted a little sister," the actor has told Us.

"She already had all these plans of dressing a little sister up in clothes," he said. "But I told her, 'Honey, that means youll be more spoiled than the boys.' She goes, 'Oh, daddy, I didnt think of that!'"
