Beyonce Knowles, Wow! Wow! Wubbzy!

The singer lent her vocal talents to the Nickelodeon cartoon -- in four episodes beginning April 27 -- in which she played the lead singer, Shine, in The Wubb Girls singing group. When Beyonce told her nephew she had the role, she said: "He didn't believe me. He's like, 'Yeah, right, Auntie BB, you don't know Wubbzy!'"
