Closer magazine reported Tuesday that "Keeping Up with the Kardashian" star Kim Kardashian allegedly caught husband Kanye West looking at sexy pictures of ex-girlfriend Amber Rose on her Instagram page.

The pregnant reality star, 34, reportedly saw West, 38, looking at Rose's Instagram page.

"Kim found Kanye looking at [it] and went ballistic," a source told Closer. "It's really damaged her confidence. He told her she was being ridiculous."

Worse, the source says that Kardashian checked the "One and Only" rapper's computer files and "found he still had old intimate pics and videos from their relationship."

Kardashian, who is expecting her second child with West, reportedly was crying and confronted him, but he assured her that it wasn't a big deal.

On Tuesday, Rose posted a new video to Instagram in which she mounts her new hot pink Jeep and twerks to the song "If You Don't Know Me by Now" performed by the Philadelphia soul group Harold Melvin & the Blue Notes. Perhaps West couldn't resist a peek, if for no other reason than amusement.

A representative for Kardashian told the Mirror that the report by Closer was a "complete fabrication."

It would seem so considering West's February radio interview with Power 105.1's "The Breakfast Club," where he dissed Rose over her remarks during a Twitter feud with his sister-in-law, Khloé Kardashian, in which Rose called his wife a "whore."

"She's just soaking in the moment," West said then of Rose. "If Kim had dated me when I wanted, there would be no Amber Rose."

He added, "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."

Kanye dated Rose for two years before they split in 2010 when she accused him of cheating on her with Kardashian. Rose said at that time Kardashian was a "homewrecker" who not only ruined her relationship with West but cheated on Reggie Bush.
