Amber Rose filed for divorce [1] from her husband, Wiz Khalifa, this week, and now the model is speaking out to clear up any rumors. On Thursday, Amber took to Twitter to address reports [2] that she had cheated on Wiz (some sources even speculated that Amber and Nick Cannon had been hooking up while they were both married). 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.....

Unfortunately my now ex husband can't say the same….

According to TMZ [6], Wiz and Amber split on Monday and have cited irreconcilable differences in the divorce papers. She is also asking for full legal custody of the couple's 1-year-old son, Sebastian. Amber and Wiz tied the knot in August 2013, and on their one-year anniversary, Amber took to Instagram to share photos from their wedding day. In a snap of them with their baby boy [7], she wrote, "Today was the day we said our vows before God and our Family. I knew as soon as I met u, u were the one for me sweetheart. Happy 1 year anniversary @mistercap and many more to come." In a more telling move earlier this month on Wiz's birthday, Amber shared another picture [8] from their wedding, this time with the caption, "Happy 27th Birthday @mistercap I'll love u forever.... Hope this year is an amazing one for u sweetheart."
