Ariana Grande and Bridgit Medler Impress at Macy's Summer Blow-Out

This past Friday was an exciting day for a few Disney and Nickelodeon stars!!

Ariana Grande and Bridgit Mendler were just a couple of the stars seen at the Macy's Summer Blow-Out at Herald Square in New York.

The two starlets were joined by All-Star Weekend and Kicking Daisies.

Ariana Grande, who plays the super fun Cat Valentine on Nickelodeon's "Victorious" did an amazing job performing Rihanna's hit "Only Girl in the World" and looked so adorable in her hot pink and red dress.

"Good Luck Charlie's" Bridgit Mendler and Shane Harper did an ah-mazing job hosting the event and both tweeted about the great time they had! We're sure the show was great!!
