The couple is set to get a divorce after rumors surfaced that cheating was involved, including talk that an alleged relationship between Rose and Nick Cannon was one of the main reasons for their breakup, according to {TMZ.}

Cannon and his wife Mariah Carey have announced publicly that they are currently separated, although they have not officially signed divorce papers just yet. Cannon announced recently that he will be Rose’s manager.

Rose took to social media to deny the rumors, saying she did not cheat.

“Please stop with the fake stories,” Rose wrote on her Twitter account. “I would never ever ever cheat on my husband in a million years I think u guys know this.” Moments later she tweeted again, “Unfortunately my now ex husband can’t say the same.”

The model filed for divorce under “irreconcilable differences,” according to {TMZ.}

Rose, whose legal name is Amber Levonchuck, wants full custody of their 1-year-old son Sebastian Taylor Thomaz, a Los Angeles County court spokeswoman told {TMZ.}

Khalifa, whose legal name is Cameron Thomaz, started dating Rose in 2011. The couple then got engaged on March 1, 2012 and got married on July 8, 2013.
