Amid explosive feud with Amber Rose, Khloé Kardashian is reportedly hooking up with her enemy's ex-husband Wiz Khalifa.

According to Celeb Dirty Laundry, the "Keeping Up with the Kardashians" star and the Pittsburgh rapper first sparked dating rumors last year, being spotted out together at a restaurant and are still seeing each other.

"Khloe is still secretly sneaking around with Wiz, and Amber knows it -- that's why she is really mad," an insider revealed. "After Amber dissed Khloé and her sisters on Twitter, Wiz totally took their side by posting pictures of her dirty house online and slamming her parenting."

Rose recently threw shade at Kylie Jenner and her relationship with rumored boyfriend Tyga during her interview with Power 105.1's The Breakfast Club. Khloé immediately tweeted to defend her half-sister.

The former stripper responded by dissing Khloé's another sibling, Kim. "@khloekardashian I'm happy u brought up the fact that I was a stripper at 15," she tweeted. "I'll be that lil whore to support my family like ur older sister is a whore 2 support hers. We're even #MuvaGivesFacts #DontPanic." The message has since been deleted.

The insider added that the battle between the two will get worse: "The feud is far from over, it is only going to get worse. This is the second man that one of the Kardashians have stolen from her."

Amber Rose previously blamed Kim Kardashian for her failed romance with Kanye West, as she told Star magazine back in 2012: "Kim is one of the main reasons why me and Kanye are not together. She's a home-wrecker!"

A source also told HollywoodLife.com recently, "It's hard to blame her, since she feels that Kanye cheated on her with Kim. Amber thinks all of the Kardashian girls are selfish and only concerned with fame."
