Karrueche Tran, Chris Brown Instagram PHOTOS a sign for making up? Karrueche refuses to delete Instagram photos of her and Chris

Karrueche Tran may still be hopeful of a possible Chris Brown hook up in the near future since she hasn't deleted their photos together off her Instagram page.

The famous couple called a quits in early March after Brown was allegedly caught sexting other women while in rehab. The "Loyal" singer was also rumored to have received secret visits from old flame, Rihanna while his Karrueche was on vacation in Turks & Caicos with friends.

According to the Confidenti@l sources say that the "Diamonds" singer visited Brown at the Malibu rehab center in late January and not in December. Rihanna jetted to the facility to check on her ex-boyfriend and only a few members on her team and a few staffers knew about the visit.

The source said Tran found out about the visit and Brown denied it at first, "With Chris in rehab, [he] and Karrueche spoke every day and she stood by his side. She took a vacation to Turks and Caicos and told friends the entire time that they were really good and happy together," the source revealed. "She trusts Chris, but when it comes to Rihanna, she has a zero-tolerance policy. Then she found out about the trip."

After revealing that she was "single," Brown tweeted, "KAE will always be my heart. That ain't changing."

Is Karrueche still keeping photos up in hopes to rekindle her relationship with Chris?
