Kylie Jenner and Tyga's relationship reportedly took a huge blow when the rapper was accused of cheating with model Annalu Cardoso. The pair, which started dating last year, is still together but is supposedly not on the "best terms" right now.

Sources close to Jenner and Tyga told People magazine the scandal has made the 18-year-old reality star "rough around the edges" toward the "Stimulated" rapper.

“They have a very ‘high school’ relationship and argue and bicker all the time about stuff for no reason," the source said. "And that’s because Kylie doesn’t trust Tyga after all the reports came out about him cheating."

As previously reported, Cardoso claimed Tyga cheated on the "Keeping Up With the Kardashians" star with her after meeting him on the set of a music video.

Tyga also faced another scandal when 14-year-old Molly O'Malia said during a press conference that the 26-year-old made advances at her on social media. Tyga and his team, however, said the rapper contacted O'Malia only because he was interested in possibly signing her to his label. Tyga also said O'Malia lied and said she was 17.

Jenner's older half-sister Khloé Kardashian recently opened up about the pair's romance, saying she's tried to talk to Jenner about everything that's going on.

“I ask Kylie … ‘I think you were just somewhere for New Year’s with him,’ and then like one day, they’re not together. That’s the life of an 18-year-old,” she explained. “So I stopped asking her, because it’s confusing.”
