MARK WAHLBERG: Weight for the New Movie

Move over, Will Smith, you’re not the only middle-aged Hollywood star who’s let himself go. Mark Wahlberg has been doing more snacking than weight-lifting lately and he’s showing off his new dad-bod.

The 49-year-old actor, who’s known for being a fitness buff, recently put on 20 pounds for his new movie, Father Stu. He posted a photo on Instagram showing what he looked like three weeks ago compared to what he looks like now and you wouldn’t believe it. And he’s not done putting on the pounds. He says he’s “going up another 20.”

But if you’re picturing Mark sitting on the couch chowing down on Wahlbergers, you’re wrong. He’s still working out hard, only he’s teamed up with a nutritionist who’s helping him gain weight the smart way. (Page Six)
