The hits keep on coming for “Keeping Up With the Kardashians” star Kylie Jenner. Just as the drama with 14-year-old model Molly O’Malia started to die down, a new scandal emerged: Tyga cheated on Jenner with a Brazilian model. After hearing the news, the reality star confronted Annalu Cardoso, Radar Online wrote in an exclusive report Friday.

“Kylie reached out to this girl and she demanded proof of the affair,” an insider told Radar Online. “Kylie always gives Tyga the benefit of the doubt because most of these girls that claim to have slept with him are just wanting to get famous.”

Jenner, 18, is used to these allegations. Tyga has been accused of cheating on her with transgender model Mia Isbaella, his ex-girlfriend Blac Chyna and Molly.

This time around, the youngest Kardashian-Jenner sister wanted evidence of infidelity. “She wants to see text messages and photos,” the source said. “Kylie needs to know if what this girl said is true. And if it is, she will have no other choice but to leave Tyga.”

The “Stimulated” rapper, 26, would reportedly wait until Jenner was out of the country to contact Cardoso. "He would text her and ask how she was doing, casual conversation. Then he started asking her to send pics and to meet up," an insider told Us Weekly Friday. "They hooked up a couple of times, but for the most part they would just hang out."

Their supposed tryst ended when Tyga feared Jenner would find out. "He used to find a way to see her, and that stopped," the source added. "They never officially stopped seeing each other, but she’s stopped talking to him."

Cardoso, 23, ratted Tyga out to Us Weekly Friday, but didn’t provide any proof.
