Chris Brown and Rihanna's relationship has been catnip for gossip writers, with a new corroboration of their relationship every day, but what about Karrueche Tran, Brown's supposedly girlfriend?

You could be forgiven for forgetting about her, but yes – she's still in the picture! Well, at least the Twitpic.

Chris Brown posted a tweet last night with a photo of him making a home-cooked meal, followed by a tweet by his nominal friend, Karrueche Tran, with a picture of the food and the words, Yup.. Get mad! surely addressing Rihanna.

Karrueche, who describes herself in her Twitter bio as where vietnam & the hood meet, is reportedly in an open relationship with the controversial pop star, but with rumors flying about Rihanna and Chris Brown and a possible arrest in the near future, how much longer can it really last?

Stories about Rihanna and Brown getting back together have been written almost daily since Brown's performance at the Grammy's two weeks ago. First it was about an hours-long dressing room rendez-vous, then US Weekly claimed they've been together secretly for nearly a year, and now gossip writers are just taking it as a given that they're back together, instead turning their attention to whether they'll stay together during Brown's legal trouble.

Which brings us to the next thing that could break Mr. Breezy and Karrueche up: Chris Brown mgiht be getting arrested soon.

His latest legal drama dates back to a cell phone snatching incident outside of a South Beach a few weekends ago, when he allegedly stole a female fan's iPhone after she tried to take a picture of Brown taking two groupies home with him for the night, maybe even to keep the photo from getting to Rihanna (apparently he's not as concerned with her knowing about his relationship with Karrueche?).

Then again, Karrueche (not to mention Rihanna!) has been very, um, understanding in the past about his indiscretions, which is not surprising considering that he's her mealticket – unlike Rihanna, Karrueche has no claim to fame other than being Mrs. Breezy.
