Karrueche Tran reportedly has suspicions that on-and-off boyfriend Chris Brown may be cheating on her with another woman -- R&B newcomer Jhené Aiko.

"She recently accused him of being more than friends with Jhené because he's been talking to her a lot and texting with her," a source revealed to HollywoodLife.com.

However, it looks like Tran got it all twisted, since "all the texts have been about her career and their song together."

Brown previously collaborated with Aiko on a track titled "Drunk Texting" off his sixth studio album "X," which he released last month. In the emotional, slow jam, the R&B duo sings in harmony about someone they just can't get their mind off of.

The "Loyal" hitmaker has apparently been asking "The Worst" crooner for relationship advice to maintain his romance with the model. "Chris has even been talking to her about life and how girls think," the source continued. "He's even been talking to her about how he can be a better boyfriend to Karrueche, because his therapist told him it's a good idea to talk to other people for a different perspective."

"So he's been doing that with Jhené and others too," the source added.

Moreover, the couple has an "open phone policy," which means that Tran has all the access to Brown's conversations with Aiko, "but even still, that's not enough. She's slightly threatened."

In addition, Chris Brown took to his Instagram account on Tuesday to seemingly express his frustration about his girlfriend having doubts about him. "I don't understand this s**t sometimes," he says in a video clip. "Girls want a man that all the other girls want, but then when they with the man, they get mad when all the other girls want him. The f**k?"
