It’s getting ugly! Amber Rose went on a Twitter rampage after Kanye West rudely insulted her in a radio interview on Friday morning, reports Rob Shuter of naughtygossip.

Chatting to Power 105.1’s The Breakfast Club, the controversial rapper made nasty comments about his ex-girlfriend’s sexual past.

"If Kim had dated me when I first wanted to be with her, there wouldn't be an Amber Rose," West said of the model, 31. "It's very hard for a woman to want to be with someone that's with Amber Rose... I had to take 30 showers before I got with Kim."

Rose has been in a Twitter war with Khloe Kardashian over Kylie Jenner reportedly dating the rapper Tyga who was previously married to her good pal, Blac Chyna. And now she struck back at West in a series of tweets, one of which referenced Kim Kardashian’s sex tape with then-boyfriend Ray J, as an example of the reality star’s own checkered past.
