The split between Wiz Khalifa and Amber Rose has already gotten off to a nasty start with cheating allegations and a possible custody battle, but now the starlet's friend Peter Rosenberg revealed that Amber walked in on Wiz having sex with twins. EW!

When Amber stopped by the nail salon with some pals on Tuesday afternoon, she appeared in good spirits, so we really have to hand it to her for keeping her cool after learning the latest dirt on her dirtbag hubby.

Rosenberg, a radio DJ, talked about how it all went down on Hot 97’s Ebro in the Morning segment, and he said, "I believe from my relationship with Amber, that she knew they had problems, she knew he wasn’t happy — she wasn’t happy either — but she was also like, ‘He’s touring, he’s going through a lot, and at some point we’re going to work on this again.' It’s a marriage." But then...

“Amber walked in on him with two women at the same time,” Rosenberg continued. “Twins, twin sisters, twin biological sisters." The twins in question are fashion designers Jas and Ness Rose, and in a sorta suspicious move, the ladies deleted the below Instagram photo of themselves with the rapper earlier this year.

Rosenberg added that Amber caught her adulterous hubby at a residence that was theirs pre-split. "It wasn’t some new home that was just his,” he said. “It was a home that he had. That she slept in. That’s how she got in. She had a key. This wasn’t some separate thing. It’s a place she goes to.”

So what about the rumors that Amber is getting down and dirty with Nick Cannon? "You all can say what you want about Amber Rose. Amber Rose is a smart-ass, savvy businesswoman who, before any of this happened, she was hustling," he concluded. “She signed with Incredible, Nick Cannon’s company. She would never then sleep with the dude that she signed with.”

Rose filed for divorce from Khalifa last week after fourteen months of marriage. They have a five-month-old son, Sebastian Taylor Thomaz.
