We can't keep up with the state of Rihanna and Chris Brown's relationship. They haven't even officially confirmed that they're together and they already seem to have called it a day.

Charming.

Rihanna went on to delete the tweets, but we reckon they were definitely aimed at Chris Brown after he was pictured clubbing with his ex girlfriend.

We can kind of understand why Rihanna would be a bit miffed about that.

We're not sure when that word became a term of endearment but let's face it, Rihanna and Chris Brown aren't your average couple.

She tweeted the words alongside a photo of her lying in Chris Brown's arms which, frankly, is making US pretty miffed.

We're exhausted by the whole ordeal so we have no idea how RiRi has the energy for this emotional rollercoaster. We wish she'd just make her mind up.
