Butt enhancement went awry in QueensLadies, if we've said it once, we've said it a million times -- if you really must have your butt enlarged, pick an expert who knows your ass from his elbow.

Tania Solis is suing Bell Stetika Spa in Elmhurst for "disabling injuries" she received during a procedure there to fix a case of pancake posterior, according to the Daily News.

This is most puzzling news for spa owner Alejandro Moreno, who insists his business does not perform any invasive procedures or anything involving needles -- only massages and the occasional bit of nutritional advice.

However, the spa's Web site offers "buttock augmentation," described as "embossment of buttocks with absorbing glasses, firming vitamins and (hyaluronic acid)."

With mysterious absorbing glasses (what the eff is that?!?) embossing butts left and right, it was only a matter of time before something went horribly, hilariously wrong. Sorry Solis, we didn't mean to turn you into the butt of the joke. (Zing!)
