Celebrity Mound

Kevin Federline says he was just as shocked as the rest of the world when those infamous photos showing his expanding waist line while emerged last spring.

“When I saw this picture, I did not think I was this big,” he told Entertainment Tonight. “I thought it was Photoshopped, you know? And then I realized that I was just letting myself go.”

Federline, whose media-given nickname went from “K-Fed” to “K-Fat,” admits he “let go” and tipped the scales at around 240 pounds after enduring a high-profile divorce and custody battle with ex-wife Britney Spears.

“I went through a lot of things and I definitely say that those things contributed to my weight gaining for sure,” the 31-year-old said.

Though Federline remains mum on how much weight he’s lost since joining VH1′s “Celebrity Fit Club,” he credits his two sons with Spears – Sean, 5, and Jayden, 4 – for helping him get back into shape.

“It was easier to eat more when they were younger because they weren’t as active,” said the former dancer, who admits to barely being able to make it up the hill on the side of his house while at his heaviest weight. “Now all of them want to play sports, hit the T-ball and run around the backyard and ride bikes.”

Federline joins a motley crew of famous faces, such as Bobby Brown, Sebastian Bach and former “Baywatch” beauty Nicole Eggert, on the seventh season of “Celebrity Fit Club: Boot Camp,” which premieres Feb. 8 on VH1.

As America embarks on a New Year full of resolutions to lose weight and make tough life changes, VH1 celebrates the new decade with a fresh season of “Celebrity Fit Club: Boot Camp.” This season boasts a cast full of pop culture personalities ready to bare their bodies and souls as they dig in for the most grueling fitness program on television – designed to help them drop not only their flab, but also their emotional baggage. At the end of eight weeks, they will be lean, mean, Fit Club machines ready to face the world and show off their new hard bodies.

Battling the bulge this season are legendary R&B bad boy Bobby Brown, Jay McCarroll (winner of “Project Runway”, Season 1), KayCee Stroh (“High School Musical”), dancer and choreographer Kevin Federline, former “Baywatch” babe Nicole Eggert, Sebastian Bach (Former lead singer of Skid Row), actress Shar Jackson (“Moesha”), and infamous “Bad Girl” Tanisha Thomas (“Bad Girls Club”, Season 2). The cast will be broken into two teams, competing for $200,000 in cash and prizes and the individual celeb who drops the most weight will win $50,000 in prizes.

That’s what the owners of a Tarzana, Calif., home are claiming after Britney Spears’ ex, who had been renting the property, allegedly skipped out on six months rent – and left the place in a disgusting mess, according to TMZ.com.

The owners are demanding $110,661 in back rent and damages, saying that K-Fed, among other tenant transgressions, left behind cigarette butts and empty beer bottles, spit marks on the exterior paint, drawings on the walls, dead tree and plants from not watering, plus broken tiles, appliances and light covers.

The unidentified owners – who fired off a letter to Federline threatening him with a lawsuit – are said to be especially upset that he never returned the garage door opener.

The owners may want to track their former tenant down on the set of the upcoming season of “Celebrity Fit Club,” on which Federline – who has gained a huge amount of weight since his split with Spears – will be one of the contestants.
