Selena Gomez and Gucci Mane?

Did Selena Gomez cheat on Justin Bieber...with Gucci Mane?

There are rumors flying that while she was filming her movie Spring Breakers in 2012, Gomez was getting up close and personal with the Atlanta trap rapper, who has a role in the film playing a criminal.

HollywoodLife claims that Gucci and Selena would spend hours in her trailer alone.

“We thought it was [odd] that she was in there with [Gucci]. One time [producers] sent security to make sure she was OK," an insider claims. “It almost became a joke, [another employee] said [to Gucci] ‘Watch out or I’m telling Justin [Bieber].’ [Gucci] was like ‘F*ck that lil n***a.”
