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.'

For viewers who might remember JoJo from 'Leave (Get Out)' and 'Too Little Too Late,' the singer says that her sound has evolved considerably over the last several years. Of 'Disaster,' she says, "The song is just more aggressive than the pop records that I've come out with before. It's still a pop record, but it's not as polite."

In the behind-the-scenes clip, JoJo looks stunning in a short black mini-dress and knee-high black leather boots, whipping her hair back and forth (an homage to Willow, perhaps?) as she belts out the bridge. Director Benny Boom explains, "Now she's grown up, so I want to give her a visual that matches where she is, in her maturity and her life." JoJo adds, "This isn't my first ride around the merry-go-round. I wrote basically this whole album, so if I'm not involved in the creative aspect of how we represent it, I wouldn't feel comfortable."

We love that JoJo's taking such an active role in developing her image and sound — and this clip is a promising look at the video that should help herald her long-overdue return to the spotlight. Her third studio album, 'Jumping Trains,' is due out in early 2012.
