Cat

Prepare to meet the most childlike, flighty, and uber emotional Cat you've ever seen! Cat's ditzy, sensitive personality makes it extremely hard for her to accept criticism of any kind, making it a bit of a mission for her friends to be completely honest around her. But though she may not be the sharpest tool in the shed, her sweet, naive demeanor and bubbly attitude makes her a star friend.

Cat is played by Ariana Grande. Before starring in Victorious, Ariana played the memorable Charlotte alongside co-star Liz Gillies in Broadway's 13. She has also guest starred on iCarly, and plays Princess Diaspro in the Winx Club. Apart from acting, Ariana pursues a singing career as well.
