Amidst her heated Twitter beef with Karrueche Tran, Rihanna has reportedly gave ex-boyfriend Chris Brown an ultimatum to dump his currently girlfriend and take her back.

According to the Star, Rihanna told Breezy to dump the Asian model within two weeks.

“Ditch her within two weeks or I’m gone for ever,” Rihanna told Breezy.

“Rihanna wants to be with Chris. She has told him to get rid of Karrueche within two weeks,” the Star sources said. “There’s a good chance Chris would be with Rihanna if she could be open about it. But until she’ll walk a red carpet on his arm, he won’t think about taking Karrueche out of the picture.”

Rihanna and Chris Brown shocked their fans last month when they release two remixes for their respective singles “Birthday Cake” and “Turn Up The Music.”

Last weekend Rihanna tweeted some Beres Hammond lyrics prepping the public for whats to come. “They Gonna Talk,” Rihanna tweeted, before following with another tweet. “When they see me with you, wonder what the crowd would say? When they find us together, what will all the people say?”

Who do you think Chris Brown should choose, Rihanna or Karrueche Tran?
