Ehh. Since everyone's known the punchline for weeks, the K-Fed burger-flipping freestyle was all anti-climax. Still: good shew, lad. And rapping at the security cam was a nice touch. Plus, now we know what to taunt dude with when the former Mr. Spears shows up for an "anti-valentine's" promotion at Boston's Gypsy bar this week. Hyping their guest as the "biggest ex of the year" and "America's most hated," Gypsy's offering access to a VIP room and a shredder to anyone who brings a picture of their ex-gf or -bf. Their "Shred Ex with Fed Ex" party goes down February 9; Gypsy's at 116 Boylston St in the Theater District. We will, of course, have a full report from the scene.
