Just when we thought the breakup rumors in hip-hop were over, Amber Rose and Wiz Khalifa are calling it quits.

After 14 months of marriage, Amber Rose filed for divorce from the 'We Dem Boyz' rapper on Monday (Sept. 22), citing "irreconcilable differences," TMZ reports.

But that's not all. Amber is seeking full custody of their 1-year-old son, Sebastian. She will only allow Wiz visitation rights.

One thing that is interesting about this case is the prenup, which Amber reportedly won't fight as it also includes spousal support. In other words, Wiz doesn't necessarily get to keep everything in this divorce.

What set off the breakup? Could it be the rumors regarding Amber and Nick Cannon being involved? According to reports, the two have been getting close since Nick signed Amber to his management company. Nick has been hit with his own marriage troubles as well. However, neither party has confirmed or denied the claims of infidelity.

TMZ also has posted a video of Amber walking around without her wedding band yesterday.
