If you can’t tell from the video, the girl’s famous guest is JoJo – the once 13-year-old sweetheart who took the Billboard charts by storm.

Here’s a video of her JoJo’s hit “Leave (Get Out)” from her 2004 debut JoJo.

Though JoJo, now 25, haven’t produced an album in literally a decade, the teen star recently released a “tringle” bomb on us last year, with three new singles at the same time. So it’s possible that JoJo might use this tour as an opportunity to debut more singles from her third LP.
