Did Selena Gomez cheat on Justin Bieber with rapper, Gucci Mane?

Selena Gomez has been accused of having a relationship with another man, while she was seeing Justin Bieber.

The allegations have emerged as she started the promotion trail for new her film, Spring Breakers.

They said what

According to a source that worked on the film, the former Disney star may have had a relationship with her co-star, Gucci Mane, as the couple would apparently spend hours alone together on set.

We thought it was [odd] that she was in there with [Gucci]. One time [producers] sent security to make sure she was OK.

The film was made back in June last year, when Selena was still officially dating the Believe singer.

The source even went on to allege that they overheard another member of the filming crew teasing the rapper about the supposed relationship.

It almost became a joke, [another employee] said [to Gucci] Watch out or Im telling Justin [Bieber]. [Gucci] was like F*ck that lil n***a.

How very odd. Surely Selena was too busy learning her lines to get down to any naughty business.

Meanwhile, former beau Justin kicked off his world tour in Manchester on Thursday and will be playing his final gig there tonight beforeheading over to Liverpool.
