Carly Shay is a fun and friendly web host who's as gorgeous as she is cyber savvy. And Tori Vega is a bold and beautiful starlet-in-training who's got a serious set of pipes.

He plays Steven in iParty with Victorious; the two-timer who shows up in the lives of BOTH of these ultra talented glamor gals. But which pair do you think makes the cuter couple?
