NEWS/ Inside Wiz Khalifa & Amber Rose's Split: Nick Cannon Was Not Involved, Couple Have Had "Issues for Some Time"

If the news of Wiz Khalifa and Amber Rose's split caught you off-guard, you're not alone.

The two PDA-friendly celebs didn't seem to hint at any trouble in paradise, but following the news of their surprising divorce, E! News learns that the famous pair "have had martial issues for some time now."

"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," a source tells E! News. "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."

There are rumors that Wiz (real name Cameron Jibril Thomaz) was unfaithful, but these allegations weren't mentioned in Rose's divorce papers.

Some reports began speculating that Nick Cannon may have had some sort of involvement in the breakup since Wiz and Amber's split comes shortly after learning that he has become Rose's new manager, but E! News is told that Cannon has nothing to do with the couple calling it quits.

"Amber and Nick are not involved," the source tells us. "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."

Amber has stayed pretty quiet since the news broke this morning, but was snapped by shutterbugs in Beverly Hills yesterday. The curvy blond, who noticeably wasn't wearing her wedding ring, flashed a smile for the cameras after copping herself some goodies at lingerie store Wolford.

Meanwhile, Wiz has just been tweeting inspirational (and possibly cryptic) words to his fans. "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," he wrote.

According to the divorce docs, as obtained by E! News, the 30-year-old cited irreconcilable differences as the reason for the split and said the two officially parted ways on Monday. Amber is asking for full legal and physical custody of their son Sebastian although she is willing to give the Blacc Hollywood rapper visitation.
