Kevin Federline has gone from K-Fed to K-Too-Well-Fed. The former back-up dancer has been out of shape for a while, but recent pictures on TMZ show that he's passed the out-of-shape phase and has completely Brandoed.

According to TMZ, Federline will take part in the next "Celebrity Fit Club," where he'll be joined by Bobby Brown, Nicole Eggert and Shar Jackson (you know, the other lady with whom he has children). And if you're dying to see what happens when the pompously-plump Federline encounters the famously-outspoken Brown, you're not alone.

Vh1's "Celebrity Fit Club" has featured such stars as plus-size model Mia Tyler, singer Carnie Wilson and actors Daniel Baldwin, Gary Busey and Bruce Vilanch. Keep up on the latest "Celebrity Fit Club" news with AOL Television.
