Are Chris Brown and Karrueche Tran engaged? Karrueche Tran and Chris Brown might have announced their engagement over the Christmas holidays.

Chris Brown and Karrueche Tran have been dating on and off for a while, but Karrueche Tran set off some Chris Brown engagement rumors after she posted an Instagram selfie of two diamond rings.

Tran wore an oval-shaped diamond ring on her right index finger in one Instgram Selfie and smaller cushion-cut diamond ring in the other.  Karrueche put a heart emoticon and a googly eyes emoji as a caption.

Karrueche Tran has sparked rumors she's engaged to her on-and-off boyfriend Chris Brown. On Thursday evening, December 25, the model posted a photo of two giant diamond rings on Instagram.

Chris Brown and the 26-year-old model were seen leaving the Playhouse Club in Los Angeles together on Wednesday. TMZ posted a video of Karrueche and Brown leaving the club and getting into separate cars. TMZ reported that Karrueche was hosting a holiday party and toy drive.

Karrueche Tran and Rihanna were reported to be "fighting a battle" over Chris Brown. Speaking on the talk show "Just Keke," Tran said the pressures of falling in love with RiRi's ex came out of the blue.

"I've never dated a celebrity before," Tran said  "so it was a very new to me. Paparazzi and all that. And then, even the situation with Rihanna, you know the reason why people tuned into this so much was because it's relateable. I have girlfriends, I have family who's gone through the same situation."

Tran continued, "It's the case of the ex. We all go through it, do you know what I'm saying? But, however ... in this case my boyfriend is a celebrity who's ex-girlfriend is an even bigger (celebrity.) So not only am I fighting a battle with her, I'm fighting a battle with 14 million fans or however else. So, imagine how that feels for me when I gotta get on Twitter and see a bunch of stuff."
