Kevin Kederline -- whose fattishness is now worse than we previously thought -- shocked and horrified onlookers at the X Games Celebrity Classic with his fantastically immense girth.

At one point at Ryan Sheckler X Games Celebrity Classic, an employee on the grounds saw Federline and remarked, "Man, that's a belly on him! That's K-Fed?!?"

While other celebrities like Verne Troyer, Frankie Delgado and Josh Henderson participated in competitive activities, Federline, 31, spent some time with girlfriend Victoria Prince sitting on a shaded patio sipping vodka and orange juice cocktails and smoking cigarettes. (Source)

The best part of the story is that Verne Troyer, who is basically handicapped, was able to compete athletically but K-Fed couldn't get his fat ass off the patio. The only way this story could possibly be any more pathetic is if "Popozao" was somehow involved.
