*Amber Rose has put her foot down via Twitter to deny rumors that she cheated on her future ex-husband, Wiz Khalifa.

The model, 30, who filed for divorce from the rapper on Tuesday, tweeted Thursday: “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…”

Rose, real name Amber Levonchuk, cited irreconcilable differences in her divorce petition and is seeking full legal and physical custody of the couple’s 19-month-old son, Sebastian, with visitation for Wiz. Their prenuptial agreement lays out terms for spousal support as well, according to court documents.

“I’m devastated and crushed but my main focus is Sebastian,” she added. “Thank u for all the support in this difficult time.”

Wiz, 27, didn’t directly respond to Amber’s tweets but decided to take a more positive approach on social media.

“Today is a magical day for many of us. Let it be yours too,” he tweeted a few hours after his wife’s tweets showed up, then he posted a photo of himself with a French bulldog that he captioned, “Smile for the day.”
