Happy birthday, JoJo! She’s all grown up!

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 is set to release her third studio album, Jumping Trains, in early 2012. Her first single off the album, Disaster, was released in September 2011 and quickly jumped onto Billboard’s Hot 100 singles chart.
