What Queen Latifah does in Vegas, stays in Vegas -- at least for now.
The actress-rapper-singer will make a cameo appearance in Fox's "What Happens in Vegas ... ," starring Ashton Kutcher and Cameron Diaz.
The romantic comedy is about two people (Kutcher, Diaz) who discover after a night of debauchery in Vegas that they've gotten married, with one of them hitting a jackpot after playing the other's quarter.
