Chris Brown's exes narrowly avoided a SUPER awkward run-in last night at a Hollywood nightclub, but Karrueche Tran took the high road when the infinitely more famous Rihanna arrived.

Karrueche Tran arrived at Greystone Manor Sunday night around 1:00am and spent only 30 minutes inside because her rival Rihanna arrived at 1:30am so Ms. Tran gave up and ditched the club rather than face her nemesis.

A source inside the club tells X17online: "One of the doormen sent word to Karrueche that Rihanna had just arrived. Karraueche kind of laughed and she and her friends basically hauled ass out the door. She definitely didn't want to see Rihanna face-to-face."

Even though Rihanna is apparently dating Drake now, we're guessing she wasn't happy to see Karrueche posting a video of Chris Brown calling her from jail telling her how much he loves her. When we asked Karrueche about that, she smiled and said nothing!
