Has Kevin Federline gained back some of the 28 pounds weight he recently lost?

The rapper-dancer, 32, celebrated Cinco de Mayo at a Mexican eatery in Chatsworth, Calif. on Wednesday.

The ex-husband to Britney Spears and dad to her two kids appeared to be sporting a plump-again physique.

After shockingly flabby photos of Federline surfaced last spring, he agreed to sign on for VH1's Celebrity Fit Club, which aired its finale last month. "I looked pregnant," he told Entertainment Tonight of the so-called "K-Fat" photos. "At my biggest, I was over 240."

He admitted that personal drama -- including his 2006 divorce from Britney Spears -- led to his weight gain. "I went through a lot of things," he said.

He dropped 28 pounds while on the weight-loss series, which also starred his ex Shar Jackson.
