According to insiders, Kim, 34, was shocked to discover rapper Kanye, 38, looking at ex-girlfriend Amber Rose’s Instagram page.
A source told Closer: “Kim found Kanye looking at [it] and went ballistic. It’s really damaged her confidence. He told her she was being ridiculous.”
If that wasn’t enough, Kim is then said to have discovered Kanye hasn’t quite let go of his past with Amber.
“She then went to his computer and found he still had old intimate pics and videos from their relationship,” the source continued.
“Kim was sobbing and confronted Kanye, telling him he had betrayed her, but he reassured her none of it was a big deal.”
Reality TV star Kim had a turbulent time when she was pregnant with their two-year-old daughter North, and it’s thought that the pictures of Amber have made her feel even more insecure about her body this time around.
Meanwhile Kim recently found herself at the centre of Nicki Minaj’s Twitter spat with Taylor Swift – much to Kanye’s amusement.
Following the announcement of the MTV VMA nominations, Nicki posted a cryptic message about the double-standards in the music industry.
Taylor took offence to Nicki’s words, assuming it was a blatant dig at her – and Kim then posted an ill-timed picture with a comment referencing Kanye’s famous interruption of Taylor’s acceptance speech in 2009.
A source told HollywoodLife.com: “Kanye thinks Kim should speak her mind and challenge people more than she does.
“He’s always telling her she shouldn’t be afraid to mix it up with people she doesn’t agree with.”
