In a totally unexpected move that no-one saw coming, the former Girls Aloud star emerged from backstage for an impromptu performance of Heartbreaker at with her former manager/BFF‘s gig, marking the Geordie singer’s long-awaited return to music.

30-year-old Cheryl, who recently nabbed an exciting new TV role on Corrie, was met by screams from thousands of fans as she sidled up to her long-term pal for a sing-song in one seriously sexy ensemble.

Dressed in a super short sleeveless black tuxedo dress and a pair of racy black thigh-high boots, the former X Factor judge topped off her flesh-flashing stage outfit with dark, smoky eyes and a slick bright red lippie and high-volume hair pinned back into an on-trend quiff. Hot.

Despite rumours that the two weren’t on great terms after parting professional ways earlier this year, Cheryl and will.i.am seemed totally smitten as they were reunited on stage.

It’s been eight-months since Cheryl left the world of music for the bright lights of LA, but with her now back in the studio recording her fourth album and back on stage with her former pop pals, it won’t be long before Lady Cole’s full return to the musical limelight begins.
