Pop star Ariana Grande has sparked rumors of a new romance with frequent collaborator Big Sean following her split from singer Jai Brooks.

The Way hitmaker, 21, became friends with the rapper last year (13) after working together on her single Right There, while they recently teamed up again on her new summer smash Problem and her next release, Best Mistake.

Reports suggest they have since grown so close, they have started dating.

The pair was snapped leaving a Los Angeles movie theater together earlier this month (Aug14) after catching a screening of action thriller The Purge: Anarchy, and eyewitnesses tell Eonline.com the stars shared a kiss during the film.

Grande reportedly ended her on/off relationship with Brooks in late July (14), not long after reconciling.

Big Sean, 26, has been single since calling off his engagement to Glee actress Naya Rivera in April (14). Rivera has since rebounded with actor Ryan Dorsey, with the pair tying the knot in Mexico in July (14).
