Amber Rose has filed for divorce from Wiz Khalifa this week after just 14 months of marriage, citing irreconcilable differences. While both camps remained tight-lipped as to what have actually caused their marriage to crumble, multiple sources are saying that both recording artists are each accusing the other of cheating.

Khalifa reportedly believes Rose was cheating on him with Nick Cannon, according to TMZ.

Just last week, a representative for Cannon  confirmed to E! News that Rose is a client under "The America's Got Talent" host's NCredible Entertainment Management team. Rose also recently made an appearance in the 2014 comedy-drama musical film "School Dance," which is directed, written and produced by Cannon.

But sources close to Mariah Carey's estranged husband  told TMZ  that Cannon and Rose have kept their relationship strictly professional.

Hollywood Life's source supported that claim, saying, "Amber has a horrible reputation. She and Nick aren't hooking up but he's hooking up with girls left and right."

Hollywood Life's tipster, however, said, "I wouldn't be surprised if they do [hook up] because they've been spending tons of time together."

There is also a report claiming that Rose is not merely Cannon's client, and that the 30-year-old model-actress has actually fallen for the comedian.

"Amber has had a crush on Nick since forever," a source told MediaTakeOut. "He was like a mentor to her, and I think she fell in love."

MediaTakeOut's source claimed that Rose and Cannon's relationship only started when the latter split from Carey.

"Nick was faithful to Mariah, and Amber was with Wiz so nothing came out of it. Then Amber got pregnant and the two just kind of drifted apart... But when Nick [and Mariah] broke up, they connected," explained the insider.

Meanwhile, sources connected with Rose told TMZ that the "Gang of Roses 2: Next Generation" star has strongly suspected that Khalifa is cheating on her since the start of the rapper's tour in July.

Rose has been reportedly telling her friends that she wanted to join the 27-year-old "Black and Yellow" hitmaker on the tour but he came up with several excuses, the most frequent of which was that she should stay at home to take good care of their 1-year-old son Sebastian.

In addition, sources told the celebrity gossip site that Khalifa tried to show dominance in their relationship by telling Rose that he was the bread winner and he needed to be left alone to make a living for the family.
