JoJo

Ever since her hits 'Leave (Get Out)' and 'Too Little Too Late,' the world has kinda missed JoJo and her soulful, wise-beyond-her-years voice. When she released a single 'Disaster' in the fall, we thought she was back -- but it turns out it wasn't her time just yet. Until now.

It's hard to believe, but even though JoJo recorded her first hit single eight years ago, she's still only 21 years old. Now, six years after her last proper album, JoJo is back with a sexy new song called 'Demonstrate,' perhaps the most "adult" track she's ever recorded.

JoJo Dishes on 'Jumping Trains' + Her Most 'Painful' Experience

JoJo closed out her Hard Rock Cafe club tour in Chicago on Wednesday, including yet another skillful cover in her live acoustic set. This time, the 20-year-old tackled Lady Gaga's 'Paparazzi.'

JoJo continued her string of impressive covers when she took on Amy Winehouse's 'You Know I'm No Good' at her recent Detroit, Mich. concert.

Remember when JoJo sang in front of her locker at school? She's come a long way! JoJo shows that she's all grown up in this new clip for her latest breakup single, 'Disaster.' The singer revealed a new, more rock-based sound on the track -- and some fierce eyeliner.

JoJo performed at the Hard Rock Cafe in Boston on Thursday, where she transformed Bruno Mars’ hit single 'Grenade' into an emotional acoustic cover.

JoJo achieves a difficult balance: The songstress manages to combine the voice of an angel with the mouth of a sailor. She may have cleaned up her act when performing 'Marvin's Room,' but her potty mouth returned on Oct. 24. The songstress performed an acoustic cover of Rihanna's 'What's My Name' at the Hard Rock Cafe in Baltimore and dropped an f-bomb.

Criminally underrated pop princess JoJo is finally set to release her much-delayed third album, 'Jumping Trains,' — and in the meantime, she's been hard at work promoting her new single, 'Disaster,' while touring with Jay Sean and Joe Jonas. JoJo sat down with Fuse TV's Top Twenty Countdown to chat about the single and preview a snippet of the Benny Boom-directed clip for 'Disaster.'

Pop songbird JoJo made a big splash on the Internet when she released her own remake of Drake's drunk-dial ballad 'Marvin's Room.' While touring with Joe Jonas and Jay Sean, the 20-year-old singer would perform her explicit rendition of the song, but lately she's been cleaning up her act.
