Chris Brown's just got totally dissed after he tried to make nice with his ex Karrueche Tran. The Loyal singer, 26, posted a sweet photo on Instagram embracing his former fling with a note thanking her for being a part of his life. "I've learned so much from you. I wish u nothing but happiness and the best," he wrote. "All I was doing was trying to fight for the woman I love."
