Looks like there's trouble in paradise for Tyga and Kylie Jenner. Just days after it was reported that the "Stimulated" rapper had been sending inappropriate texts to underage model Molly O'Malia, yet another woman is coming forward. Brazilian model Annalu Cardoso claims she had some sort of relationship with the father-of-one while he was dating Jenner, 18.

According to US Weekly's sources, Tyga, 26, met the 23-year-old model while shooting a video. She is also said to have made an appearance on his MTV2 reality show "Kingin' With Tyga." The source claims he "hit on" Cardoso, but was careful not to get caught. The rapper reportedly began contacting Cardoso via text which eventually turned into him "asking her to send pics." Another source claims they "hooked up," but for the most part were just platonic friends.

"Tyga is very careful and waits until Kylie is out of the country," sources said.

Whether or not the pair were consistently hooking up, Us' sources claim Tyga introduced Cardoso to several friends. They were reportedly careful not to be "extremely affectionate" but the rapper's friends were said to be aware that there was something more between them. Tyga was also very careful not to mention his girlfriend's name around Cardoso. Sources told Us she never breached the subject with him, but he acted "like someone who didn't have a girlfriend" so she went with it. In spite of this they eventually made the decision to end their deceptive relationship. Sources claim Tyga got nervous that his infidelity would get out which eventually resulted in their demise.

On Jan. 4 teen model O'Malia came forward claiming she had been contacted several times by Jenner's boyfriend. In a press conference with lawyer Gloria Allred by her side, the 14-year-old stated that she only entertained Tyga's advances because she believed he was interested in furthering her music career. Once it became clear that he had other motives O'Malia became nervous. She said she declined his requests for video chat sessions and cut off communication with him after asking three times. O'Malia also criticized OK! Magazine for publishing their text message conversation and not trying to conceal her identity.

Neither Tyga nor Jenner have addressed Cardoso's comments. There is no further proof that the pair were together during his relationship with Jenner.
