After it was confirmed that Amber Rose had filed for divorce from her husband of one year, Wiz Khalifa, new details have surfaced citing cheating as the reason for their split.

According to TMZ, the model-turned-actress is convinced that the "Black and Yellow" rapper has been a "serial cheater" for months. The site reported that sources close to Rose say that since the beginning of Khalifa's tour in July, she was already convinced that he was being unfaithful. She told friends that she wanted to join him on tour but he came up with a host of excuses convincing her to stay at home with their one-year-old son, Sebastian.

Though Rose appears to be the accuser, reports also claim that Khalifa believes that she was also stepping out with her now-manager Nick Cannon and is tossing around the allegations to cover up their relationship. Cannon, however, is denying it all, stating that their relationship is strictly platonic and that he learned of their split through her lawyers.

Rose took to Twitter on Thursday morning (Sept. 25) to clear her name, further confirming that her rapper husband was unfaithful.

"Please stop with the fake stories. I would never ever ever cheat on my husband in a million years. I think u guys know this. Unfortunately my now ex husband can't say the same," she tweeted before thanking her followers for their support.
