More than Kevin Federline‘s little piggie has gone to market, much more. The once thin, althletic backup dancer has totally let himself go — and he doesn’t care.

Shar Jackson was at HBO’s post-Emmys party in Los Angeles on Sunday and said,

“He doesn’t care. The beautiful thing about him is that he could care less.”

As his ex Britney Spears continues her Circus tour, he’s been on the road looking after their sons Sean Preston, 4, and Jayden James, 3. — This is his meal ticket.

Jackson said that he still manages to phone the two children he has with her: Kori, 7, and Kaleb, 5.

“He calls them all the time. They have good long phone conversations. I’m like, ‘Ok, that’s good. Hang up the phone ’cause we have stuff to do.’”

of course not, he has nothing else to do but call the kids and eat. I’m sorry, that was unfair… he golfs and goes bowling too.
