JoJo unveils new song 'Demonstrate' - listen
'Demonstrate' will be available to buy from August 28 and is taken from the singer's much-delayed third album Jumping Trains, which is scheduled to be released later in the year.
The track was produced by Drake collaborator Noah '40' Shebib.
Lyrics include: "I can't say / but I know I can demonstrate / I can let my body explain / I know I can demonstrate."
JoJo previously released 'Disaster' - which will also feature on Jumping Trains - and 'Sexy To Me'.
Speaking of her new album, she said: "My third album will be called Jumping Trains and it's very symbolic for a variety of reasons.
"Moving from Boston to L.A., transitioning from being a girl to being a young woman, living on my own, taking a different direction sonically, and just really finding myself and just jumping into a new chapter of life."
