Sigh... how time flies. One day you're sitting in front of the TV LOL-ing with your new fave redhead on the premiere of Victorious and the next you're watching her shine in her own spinoff series! If it sounds like we're talking about the one and only Ariana Grande, then hats off to you, 'cause we are! Since her early days as Cat Valentine on the set with Victoria Justice and the gang, we've been going Bibble-over-heels crazy for this star. And now, we can't believe how far she's come!
