Rumors are swirling that Chris Brown and on-again/off-again girlfriend Karrueche Tran are engaged after she Instagrammed a photo of a giant diamond ring on her hand on Christmas day. If this is the case, these two are officially worse than Justin Bieber and Selena Gomez!

Earlier this month Chris and Karrueche broke up yet again, and he blasted her on Twitter for hooking up with Drake, but those messages have since been deleted. "We've got scars, some of them u gave me, some of them I've caused," he wrote. "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!"

For her part, Karrueche wrote, "I refuse to be repeatedly mistreated especially by someone who claims to love me. That's not love. And if that's what you define as love then I don't want it. Yes, I have not been so smart before in the past but I made a promise to be a better and stronger woman and I'm keeping that promise. If you can't love me the right way, then don't love me at all."

The singer tweeted a lengthy apology the next day, so maybe one (or both) of these rings were yet another attempt to win Karrueche back? It's worth noting that they aren't on her left hand, so they could also just be promise rings. Hmm...
