Amber Rose didn’t know what “true heartache felt like” until she split from Wiz Khalifa.

The 30-year-old model took to her Twitter account this morning (06.10.14) to express her devastation over the end of her marriage and even compared her emotions to the pain felt when a “best friend” passes away.

She tweeted: “The mornings are especially hard.

“The pain…I wake up every morning feeling like my best friend died….. I never knew what a true heartache felt like until now. (sic).”

Amber filed for divorce from the 28-year-old rapper – whose real name is Cameron Thomaz – last month, citing irreconcilable differences.

However, since then, Amber’s best friend DJ Peter Rosenberg claimed that the couple split after the blonde beauty caught her spouse cheating on her with twin sisters Jas and Ness Rose in their family home.

He said recently: “Amber walked in on him with two women at the same time. Twins, twin sisters, twin biological sisters.”

Although, he admitted the couple – who have 19-month-old son Sebastian together – had been unhappy for some time, but Amber was hoping they could work through their problems once Wiz had finished touring.

Meanwhile, rumours that Amber had cheated on Wiz, whom she married 14 months ago, have also been circulating in recent weeks, but she has since shot down the “fake” allegations in a series of tweets.

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…. I’m devastated and crushed but my main focus is Sebastian. Thank u for all the support in this difficult time. (sic).”
