"I grew up—Shouldn’t you?"

Since its inception in 1953, Playboy has been the gift that keeps on giving to men around the world. However, that’s not to say that every Playboy model has been as sizzlingly attractive as Joana Krupa. In fact, sometimes Playboy sets its sights on sad, attention-starved starlets simply for the PR. Take Tara Reid, for example. Her spread will draw in many readers more interested in the train wreck than the scintillation. Similarly, sometimes Playboy snags some real hotties, but only gives us a small slither of nudity pie – not exactly what “readers” are seeking from the magazine. As 2009 draws to a close, we decided now is as appropriate of a time as ever to compile some of Playboy’s worst cover girls in the mag’s history. Of course, for the record, we’d probably still sleep with them all.

Shannen Doherty's rebirth into the spotlight is cause for celebration, no doubt. Couple that with an appearance on the cover of Radar's October issue, and the only kind of fête to do it justice is an event tomorrow night at a WWII-inspired, spelling impaired Flatiron bar, Catch-22. And judging by the tiny logos on the bottom of the invite, suds are courtesy of Blue Moon, vodka by Tito's. David Barton Gym is hosting the event, and are deploying their personal trainers to make sure each beer is accompanied by 1,000 crunches. For a whiff of Ms. Doherty's hair and a brand new six-pack, rsvp to {encode="rsvp@rosengrouppr.com" title="rsvp@rosengrouppr.com"}. Party runs 8-10 p.m.
