Rapper Wiz Khalifa reportedly will write a diss song about Amber Rose once their divorce is finalized, the Hollywood Life reports.

Though the "We Dem Boyz" rapper has continued to post positive messages on his social media accounts and has yet to discuss the couple's shocking split, a Hollywood Life source reveals that Khalifa is simply "lying in wait" until he can hit back at Amber Rose in his music.

"Wiz will definitely write a song about Amber, but he wants to wait until the divorce is finalized," the Hollywood Life source said, "because he doesn't want to give her any more ammunition to use against him."

According to the Hollywood Life, Khalifa was originally not planning to diss Rose in his music. However, due to Rose's recent social media diss at her soon-to-be ex-husband, Khalifa has now had a change of heart.

On Thursday, Rose took to Twitter to accuse Khalifa of cheating. Rose also slammed rumors that she had cheated on Khalifa with her manager, Nick Cannon.

"Reliving that moment over and over and over......smh," she wrote.

"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....." she said, "Unfortunately my now ex husband can't say the same...."

Despite Rose's infidelity accusations, TMZ reports that Khalifa was "already under the impression" that the couple had split when Rose allegedly found him with another woman at his house that he purchased weeks prior to Rose filing divorce.

"We're told Wiz moved out and got his own place, and the day before Amber filed, she went to his house at 2 a.m. and found him with another woman ... and went nuts," a TMZ rep reported. "As far as Wiz is concerned ... he wasn't cheating. He told friends he made it clear weeks earlier the marriage was over."

Prior to Rose's divorce filing, a TMZ rep claims that Wiz had already told his friends that he "just didn't want to be married to her anymore."
