Awww, snap! Grab some popcorn and pull up a barstool: You've just landed ringside seats at an old-fashioned gossip-slinging, name-calling celebrity girlfight.
(All that's missing is hair-pulling!)
Rose first rose to prominence on the Hollywood radar in 2009, guest starring as Kanye West's other (slightly less self-centered) half. The couple abruptly called it quits in 2010.
Amber always remained mum on what (or who) drove a wedge between them in their high-profile romance. But with the blogosphere heating up with dish that a not-quite-divorced Kim K. may be secretly snuggling up to Ye, Amber's having a tough time maintaining her composure.
Aren't you glad a Star magazine reporter was around to take notes as she exploded?
"Kim is one of the main reasons why me and Kanye are not together," Amber spat during an interview for the Jan. 16 issue of the supermarket glossy. "She's a homewrecker!"
Kanye, 33, and Kim, 31, met on the set of a Complex magazine photo shoot in 2008. Almost instantly, rumors of a romance flourished. According to Amber, she was dating Kanye when the rapper eventually tasted temptation (no pun intended) and hooked up with the international sex symbol.
At the time, Kim was on the rocks with NFL star Reggie Bush -- who had reportedly cheated on the reality star with Miami-based model Carmen Ortega. Amber says it was a heartbroken Kardashian who instigated the affair with Kanye.
The Keeping Up with the Kardashians cutie allegedly began calling, texting and sending racy photos of herself to the "Jesus Walks" hit-maker in mid-2010.
"They were both cheating on me and Reggie with each other," said Amber, who is now dating "Black and Yellow" hip-hopster Wiz Khalifa.
The 28-year-old Rose, who appears in a new advertisement for Smirnoff Vodka, claims she even confronted Kim about her dalliances with Yeezy, only to be rebuffed.
"She was sending pictures and I was like, 'Kim, just stop. Don't be that person.' I thought at least she'd be woman enough to respond to me. She never responded," according to Amber.
"It's very important that us women stick together and we don't f**k each other over like that."
This is quite a different tune than the one Amber was tooting just a few weeks ago.
In November, the bald beauty was coy when asked about Kimmy's supposed fling with Kanye during an appearance on The Wendy Williams Show.
(In case you were wondering, avoiding direct questions is usually Hollywood-speak for "Heck yes!")
"I mean, come on, like you know… We'll keep it cute," she said coyly.
Rose was much more direct when quizzed about her own Kardashian-related fling.
In 2011, Amber briefly hooked up with Kim's ex, Reggie. She insists, however, that she was not the reason for their split.
"I'm not a homewrecker. I broke up with Kanye and [Reggie] broke up with Kim. We met after. We were both going through a hard time. We were each other's rebounds. It was brief, it was nice," Amber told Wendy.
Neither Kim nor Kanye have responded to Amber's allegations.
This isn't the first time Kim has been accused of sending x-rated snapshots of her hoo-ha to a famous man. Before her August nups to Kris Humphries, Bret Lockett, a star with the New England Patriots, told In Touch Weekly that Kim had embarked on an electronic affair -- filled with sexting and explicit phone calls -- with him while she was engaged to Humphries.
