Amber Rose has officially filed for divorce from Wiz Khalifa and multiple sources are now speculating that it had to do with her relationship with Nick Cannon.

A source close to the estranged couple confirmed that the two have been having some marital problems for quite some time now, even though there were no obvious indications at all, according to E! News.

"They cared very much for each other but it all happened so fast between having the baby and getting married. They really did not know each other as much as they should have before getting married. They both have not had the best pasts with relationships and when they met each other it was more lust at first sight than love at first sight," the source told the publication.

Meanwhile, Cannon, who recently had troubles with his wife Mariah Carey, allegedly told some of his friends that he is seeing Rose, Xpose reported.

However, a source close to the "America's Got Talent" host denied that the two are romantically involved and stressed that their relationship is strictly professional.

"Amber and Nick are not involved. It is just business and the rumors are false. Nick is just focused on the business side of things with Amber, nothing personal. They have never hooked up," the source explained.

As of late, both Rose and Khalifa have not yet denied or confirmed the news but the rapper has been tweeting inspirational messages lately.

"Nothing but positive energy... Your light was made to shine... That's why it was given to you... That's why it was given to you... We belong to the world," Khalifa tweeted.

Rose filed for divorce earlier this week and cited irreconcilable differences as the reason for the split, SF Gate noted.

The "Black and Yellow" rapper share his 19-month-old son Sebastian with Rose.
