JLS reveal new single
JLS have announced their first single from their third album.
It's called 'She Makes Me Wanna" and it will be released on July 24 but will get plenty of exposure before then.
The song was co-written and produced by Lady Gaga collaborator Red One.
A spokesperson said: "The collaboration came about at Alicia Keys' Black charity Ball last year when they bid £30,000 to win a session with the super slick multi-Grammy Award-winning producer and this floor-filler was the result."
