Amber Rose denies cheating

Amber Rose has denied cheating on Wiz Khalifa.

The American model filed for divorce from the rapper on Monday, after just 14 months of marriage.

And following a host of rumours circulating about the reasons for the split, Amber took to Twitter to set the record straight.

"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….. (sic)" Amber tweeted.

However, Amber continued her lengthy Twitter post to allege that it was Wiz's infidelity that led to the break-up.

"Unfortunately my now ex husband can't say the same," she tweeted.

Amber added that while she is "devastated and crushed", she is doing her utmost not to let her son Sebastian get in the middle of the split. Amber gave birth to Sebastian in February 2013 and is reportedly seeking full custody in the divorce.

"I'm devastated and crushed but my main focus is Sebastian. Thank u for all the support in this difficult time," Amber wrote.

It was previously claimed that Amber had suspected Wiz of being unfaithful from when he started his tour in July.

Sources close to the model told TMZ she had wanted to join Wiz on the tour, but he allegedly came up with a host of reasons why she shouldn't.

Meanwhile, Wiz is said to believe that Amber cheated on him with Nick Cannon, who split from his wife Mariah Carey last month.
