Miranda Cosgrove had a total blast ringing in her big birthday this year. She boogied down with the cast of iParty with Victorious and got to hang out with tons of her fabulous fans at the St. Judes fundraiser! But there was just one thing she was missing...a happy birthday from her favorite on-screen family, the cast of iCarly! Jerry, Jennette, Nathan, and Noah snuck backstage and rolled out a super sweet surprise birthday cake for Miranda while she wasn't looking. What a perfect present, guys!
