Kim Kardashian may have reason to be worried following reports that boyfriend Kanye West has his eye on young Aussie rapper Iggy Azalea.

Last year Azalea was the first female and the first non-American rapper to be featured on the cover of hip-hop magazine XXL's annual Top 10 Freshmen issue, highlighting the top new artists to watch in the genre.

Perez Hilton reports that the 22-year-old Australian beauty and West have been spending a lot of time together, and she even spoke about him last month. “I was at his house last week and he was playing me his ‘scriptures,’ as he calls his spoken-word interludes,” Azalea told The Guardian.

West is currently in France working on a music project while Kardashian remains in the States, and she is reportedly concerned about him looking at other women as she is gaining a lot of weight due to her pregnancy with his child.

"She's incredibly stressed and has even started to wonder if Kanye's cheating," a source told InTouch. "Kim is not in a happy place right now."

If West is cheating on Kardashian, it might not be the first time. His ex-girlfriend Amber Rose accused him of cheating on her with Kardashian. Kardashian was also allegedly cheating on then-boyfriend Reggie Bush with West. Rose claims the reality star sent West racy photos and texts while he was still with Rose.

"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. It's very important that us women stick together and we don't [expletive] each other over like that," Rose said in an interview with Star magazine last year.
