Relatively few boldfacers showed up for Diddy's CFDA awards after-party at Marquee last night — do Top Model winner Caridee and Danity Kane singer Aubrey O'Day count as celebs? — but Tinsley Mortimer was one of them, arriving long before Diddy showed up. Tinsley occupied her time getting cozy with new BFFs Richie Rich and Trevor Raines, engaging in some groping with the former and hoisting up her white sequined dress to do a lap dance for the latter. But then she abandoned the Heatherette duo for — huh? — that chick from Danity Kane. Presumably this was a move to get closer to Diddy, who was holding court at a table nearby. Mortimer and the Danity Kane chick danced and flirted with random passersby, perhaps angling for Diddy's attention. It didn't seem to work. Once it became clear that Diddy either (a) had no idea who she was or (b) didn’t care, Mortimer, who was perpetually perched on a banquette, fiddled with her cell phone for a while before sneaking out inconspicuously. Top Model's Caridee, meantime, stuck around on the unacknowledged outskirts of Diddy’s bevy of friends and bodyguards. —Rachel Wolff
