Kevin (well Fed) Federline’s other babay mama Shar Jackson jumped to his defense today after bloggers posted unflattering pics of K-Fed on a golf course. In one pic, K-Fed could hardly see over his ample gut to hit the golf ball. But Shar says he packed on the weight because he’s a happy stay-at-home mom now:

“It’s daddy weight!” she tells Usmagazine.com. “When you are a full time parent, sometimes you can’t focus on you.”

If gaining a few pounds is your only problem, life’s not too bad!”

Adds his rep, “He’s a stay-at-home dad, and people tend to gain weight when they are home with the kids. He’s very happy with the way he looks.”

Federline was awarded sole custody of Sean Preston, 2, and Jayden James, 17 months, in January. (Source)
