It's time for another Tuesday lunchtime edition of Whodunit. Today's meaty installment has us wondering which rehabbing socialite ditched Fashion Week in favor of the Wonderland ranch, which celeb mom has been feeding her daughter's coke habit,* which singer has been upchucking all over town and which comedian isn't as in love with his wife as he would have us believe.

Think you know which engaged celebutante missed Dolce & Gabbana to hang with Brit, or which scary skinny "soulful singer" has butterflies in her stomach but no complex carbohydrates?

Send in your best guesses and let your peers sort through all the unsubstantiated gossip-mongering!

WHICH socialite was conspicuously absent from the front row during Fashion Week because she was in rehab? The bride-to-be went to a "special spa" to conquer her cocaine habit before the wedding . . . WHICH celebrity mom joins her daughter in snorting lines of cocaine? . . . WHICH soulful singer is bulimic? Friends are concerned the stress of having a new album is causing her to throw up her meals . . . WHICH funnyman is having an affair? His wife doesn't mind - she's got her money and her status to keep her company.

*Alright, fine. That one's obviously about Dakota Fanning.
