Chris Brown and Karrueche Tran might be planning a 2015 wedding. Rumors about the on-again/off-again couple began to swirl after the 26-year-old model posted a photo on Instagram Christmas Day of two diamond rings on her right hand. Tran simply captioned the photo with an eyeball and heart emoticon, but does Brown’s Twitter account read more into the alleged engagement?

The #ChristmasChallenge that the 25-year-old recording artist is referring to is something that Instagram user @Woody_thegreat  started on Christmas Eve when he posted a video of him and his friends dancing to Chingy’s 2003 song “Right Thurr.”

“Who want this battle???” @Woody_thegreat posted.

Brown then stepped up to the plate on Thursday, replying to the video with one of his own. With his Christmas tree and gifts behind him, Brown threw out dance moves to Chingy’s song.

Other Instagram users jumped in on the fun throughout the day, uploading their own #ChristmasChallenge videos that Brown reposted on his official page. Justin Bieber even joined in with his own dance to “Right Thurr.”

While Chris Brown’s tweet doesn’t seem to be referring to an engagement to his longtime girlfriend, many are speculating that the rings Tran posted might be an “apology” gift from her beau. The couple engaged in a very public fight on social media in early December after Brown accused Tran of dating Drake on the side. Brown and Tran appeared to break up at the time, however, the singer apologized on Twitter shortly after. They were photographed together right before Christmas.
