Singer and actress JoJo, whose mature-sounding voice crooned out hits such as Baby It's You and Not That Kinda Girl, is 21 years old.

JoJo, the stage name for Joanna Levesque, is a Clearasil spokeswoman and has a new album scheduled for release in early 2012, titled Jumping Trains.

They've been so faithful, I just want to deliver for them, she said of her fans on her Web site. They deserve it. Especially the really devoted ones who have waited it out with me. I really want to make them proud. I want them to feel like Jumping Trains was worth the wait.

She got back into acting this year when she appeared on the TV series Hawaii-Five-0 in January.

Her last major acting work was in the 2006 mermaid movie Aquamarine with Sara Paxton and Emma Roberts.

JoJo was so popular with the kid crowd that Ashton Kutcher Punk'd her in 2007. She went to visit a little girl in the hospital -- who was in on the joke -- and tried to keep calm while a health alarm went off.

Here are photos of the former teenybopper. She's all grown up!
