Federline 'doesn't care about weight gain'

Kevin Federline does not care about his recent weight gain, according to his ex-girlfriend.

The former backing dancer, who was previously married to Britney Spears, hit the headlines recently after photographs surfaced showing him looking bigger than normal.

Speaking to Us Weekly, former love Shar Jackson said: "He doesn't care. The beautiful thing about him is that he could care less."

She went on to say that Federline still enjoyed a good relationship with his two children by her, Kori, 7, and 5-year-old Kaleb.

"He calls them all the time," she explained. "They have good long phone conversations. I'm like, 'Okay, that's good. Hang up the phone because we have stuff to do'."

Jackson added: "[Britney] seems like she is doing well. Good for her."
