Kevin Federline Victoria Prince

Someone's looking svelte!

On Saturday, Kevin Federline embarked on his weekly routine to cheer on his sons during their soccer game and was noticeably more trim than he has been.

The 35-year-old father, who was joined by wife Victoria Prince and their two-year-old Jordan Kay, has lost 30 lbs since July when he announced his goal of shedding 50 lbs after signing up for Fresh Diet.

Glad to see K Fed making considerable progress!
