Chris Brown and Karrueche Tran spark breakup rumors once again, after removing each other's photos on their social media accounts.

The "Loyal" hitmaker caught many eyes when he shared an extremely racy picture of his on-and-off again girlfriend via Instagram on July 4. The black-and-white image showcased Tran's flawless, nearly naked body only in a tiny black thong and a matching bra. However, Brown removed it as well as all of her other snapshots that he posted on his account.

Similarly, the R&B star's photos are nowhere to be found on the model's Instagram account. Moreover, Tran posted a couple of quote images on Sunday, July 6 that suggest the pair's falling out, which read, "Love what you have before life teaches you to love what you lost" and "In the end, only three things matter: how much you loved, how gently you lived, and how gracefully you let go of things not meant for you. - Buddha."

The couple's actions on social media follow Brown's recent frustration about Tran partying without him, when she went out to a Socialite Sundays event hosted by Brandon Anthony's Socialite House in West Hollywood on June 23. The "New Flame" singer was apparently worried about his girlfriend, while the Kill designer was enjoying her time at the gay hotspot.

"Chris was annoyed that she was out. Chris really hasn't been enjoying the club scene as of late," a source close to Brown revealed to Hollywood Life. "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."

"It more so just seemed like he kept checking up on her, very obsessively," the source added.

Despite Chris Brown's persistent texts, Karrueche Tran continued to party until 1 a.m. "Kae was drinking and dancing and having a great time," the source said. "She and Christina [Millian] had a blast. They were at a table with bottle service."
