Ariana Grande has certainly been enjoying a star-making summer. Since it premiered at the
Radio Disney Music Awards at the end of April, her hit single "Problem" has gone platinum and become the biggest song of the summer. Entertainment Weekly magazine wrote, "The only problem with Ariana Grande's 'Problem' is that it ends," and the song won Ariana so much starpower that MTV resurrected their show Total Request Live (canceled in 2008) for one day only, just to have her on it. She's kept busy touring, performing, promoting her album, and recording tracks for a new one. Although she's best-known for two Nickelodeon shows, Victorious and its spinoff Sam & Cat (costarring
Jennette McCurdy), she's been eager to embrace Disney Channel, too. On June 24, she put on Mickey Mouse ears and celebrated her 21st birthday with a party at DisneyWorld.
