It's all based on circumstantial evidence, but we're The Hollywood Gossip, not The Hollywood Fact. So check out this allegedly sordid tale:
According to MediaTakeOut, Nicki Minaj walked in a troubling surprise during her birthday party in Vegas this past December: Amber Rose in the same room with Nicki's boyfriend at the time, a dude named Safaree.
Minaj grew suspicious and thought "something was going on," according to a source, who added that the singer later grabbed Safaree's phone and found naked photos of Rose sent via BBM. We've posted one below:
Trust us, most are A LOT more graphic.
The insider says Safaree actually convinced Minaj that nothing ever happened with Amber and that she was just trying to seduce him. He and Nicki are still together...
... but the artist has allegedly ordered all other friends, including Lil Wayne and Drake, to stay the heck away from Rose. And if Nicki ever sees Kanye's ex? Look out, world!
