West Hollywood's Greystone Manor was allegedly the site of a Chris Brown and Rihanna passive-aggressive stare-off on Sunday, reports Page Six.

Brown was reportedly there with his girlfriend, Karreuche Tran, and The Game. Rihanna was there with Kevin Hart.

"Chris and Rihanna sat a few tables away from each other and shot dirty looks at each other all night," said the source to Page Six.

Rumors about the one-time couple continue to swirl following the 2009 incident when Brown physically abused Rihanna, leaving her bloodied and bruised.

The two recently collaborated on the singles "Birthday Cake" and "Turn Up The Music." Rihanna told Esquire UK that they worked together in a "completely professional environment."
