Karrueche Tran’s relationship with Chris Brown has been a hot topic over the past couple weeks.

Since the Grammy Award-winning singer was released from prison, several reports have surfaced about the details of their relationship and how things are moving in a positive direction. Just last week, the two were reportedly making strides to move in together.

Now, several media outlets are reporting the “Fine China” singer is actually quite “annoyed” with his girlfriend.

According to Cover Media, the 25-year-old singer-dancer feels some kind of way about Tran going out and partying without him.

However, a source close to Brown spoke with Hollywood Life about the most recent reason for his aggravation. The source revealed that he was quite upset about her outing last weekend with singer, Christina Milian. The ladies attended an event at the notable gay club, Rage, in West Hollywood.

“Kae was drinking and dancing and having a great time. She and Christina had a blast. They were at a table with bottle service,” a source explained to the publication. “Chris was annoyed that she was out. Chris really hasn’t been enjoying the club scene as of late.”

Tran reportedly spent a lot of time texting the “Loyal” singer throughout the night. Although several onlookers cited that Tran didn’t appear to be arguing with him, she did seem tense. The source also shared a few additional details about Tran’s cell phone activity.

“Kae was in a good mood but spent a majority of the time responding to A LOT of his texts. She even stepped outside of the club to take a call … but when she went back inside, she shut off her phone so she could really enjoy the rest of the night.”

Karrueche Tran and Chris Brown began their on-again, off-again relationship back in 2010 not long after the singer’s highly publicized break-up from singer, Rihanna.
