Reports are claiming that Chris Brown and Karrueche Tran have called it quits on their relationship for good.

Sources say that the couple went their separate ways over the weekend. While no one knows for sure why the long-time love birds have split up, it is believed that it could be over a picture that was posted on Instagram.

Chris shared a revealing shot of Karrueche on his Instagram page last Saturday. The picture shows the model lying face down on a bed dressed only in a tiny black thong and bra.

Soon after Chris deleted the picture on his Instagram, Karrueche posted a cryptic Buddha quote.

“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.”

This isn’t the first time the couple have split up, as the Tran and Brown ended their romance in 2010, but later got back together in May 2013.
