Karrueche Tran has sparked rumors of engagement with singer Chris Brown after she posted a photo showing off two massive diamond rings on her Instagram account on Christmas Day. However, the 25-year-old singer’s on-again, off-again girlfriend did not reveal if either one was an engagement ring.

On Thursday evening, Tran posted the photo of her right hand with a big diamond ring on her index finger and a smaller one on her ring finger. Brown and Tran were spotted early Wednesday leaving Playhouse Club in Los Angeles, according to TMZ, giving rise to speculations that the two may have got back together.

Reports of Tran and Brown’s breakup surfaced earlier this month after the latter declared during a concert that he is single. During the time, the “Loyal” singer also alleged that Tran cheated on him with rapper Drake.

Brown posted a message, which was later deleted, on his Instagram account, saying: "That ride or die act we have been fooling the world with obviously ain't working.

“I was locked up for damn near 4 months and only got 1 visit from you while u was hosting parties and taking secret trips to Toronto, going on dates with Drake," Brown wrote, according to a screenshot on MTV News.

Brown later apologized for the rant in another Instagram post.

“Being young and dumb is one of my strong suits and emotional at best. I love hard and react impulsively when I'm hurt at times,” Brown wrote. “So I AM APOLOGIZING I live in a glass house and the same s*** that makes me great also is my curse. Everybody know I love that girl. I don't care how my image my look to the public because I'm still gonna be the best at what I do. I just want baby girl to know I apologize!”
