While Twitter has been speculating motives behind the recently announced marital break up of Amber Rose and Wiz Khalifa, at least one side of the story has come out with Amber saying the Pittsburgh rapper's unfaithfulness is what caused the split. More specifically, Amber walked in on Wiz in bed with another woman, according to TMZ. The site reports, sources close to Wiz say things haven't been all good, with the rapper allegedly saying he, "just didn't want to be married to her anymore." Wiz reportedly moved out a day before Amber filed for divorce. According to TMZ, Amber visited his new abode in the middle of the night and found him in bed with another woman, triggering her going forward with the divorce paper work. The former video vixen is seeking full legal custody of their 1-year-old son, Sebastian. Unfortunately, the former bubbly couple is just one in a long list hip-hop couple who have gone through a breakup this year.
