Rihanna and Karrueche Tran, the love rivals who were apparently dating Chris Brown at the same time in 2012, were spotted partying at the same nightclub over the weekend.

While Tran is no longer dating the X singer and Rihanna has rekindled romance with Drake, both ex-girlfriends of Brown decided to show up at Greystone Manor in West Hollywood on Sunday night. The Vietnamese model was already inside the nightclub before Rihanna and her entourage got there. However, when she realized that the "Diamonds" singer arrived, she did her best to avoid the girl drama by immediately exiting the venue.

However, it certainly seemed that Karrueche Tran was not bothered at all by the unexpected visitor, as she was all smiles, standing by the side of the road and waiting for her ride. Also, she flaunted her slim figure in a white crop top sweater with a pair of cutout denim shorts. On the other hand, Rihanna was entirely covered up with a baggy, oversized sweatshirt and blue skinny jeans.

Back in 2012, Chris Brown famously admitted that he was in love with two women. "I'm stressed out... when you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult," he said. "Is there such thing as loving two people? I don't know if that's possible, but for me, I feel like that."

In addition, Rihanna's night out comes amid reports that she may be pregnant after she was spotted drinking decaffeinated tea, instead of coffee. The Barbadian singer reportedly has given up smoking marijuana, and she even "refused to attend the official after party on Drake's tour because there would be too much alcohol and weed smoke there."
