Leave it to Kevin Federline to let it all hang out — literally. Last night on VH1’s weight-loss realityfest Celebrity Fit Club: Boot Camp, the former Mr. Britney Spears/rap wannabe furnished shirtless “before” pics of his 232-lb. self, gamely cracking to the judges, “I look like a pregnant man.” (One is tempted to ask, a la Paulie Walnuts, whether the snaps are “before” or “way before.”) Weigh in, PopWatchers (no pun intended): Is this TMI? Are you reeling from mammal toe — or mammary overload? Does the well-fed K-Fed’s choice of camo underpants render a disservice to our men and women in uniform, or out of it? Can fellow Boot Camp-ers Sebastian Bach and Bobby Brown possibly top this feat of show-too-muchmanship? And, most terrifying to contemplate, should such exhibitionism from Britney’s ex earn a “Malibu Gas Station”-style tribute from those pop-fixated noise-rockers Sonic Youth?
