Rihanna and Rob Kardashian Flirt on Twitter

Nothing's more fun that two celebrities tweeting at each other in a vaguely flirty way, right? Right. Nothing is more fun than that.

This is an exchange Rihanna and Rob Kardashian had on Twitter late last night:

Rihanna, tweeting at "Basketball Wives" star Evelyn Lozada, letting her know she was watching "Wives": @EvelynLozada ugh! DUH!!! Popcorn and remote in hand

Rob (we're not entirely sure what he means here, but it seems suggestive): I CAN MAKE THIS RIGHT HERE HAPPEN. RT@rihanna @EvelynLozada ugh! DUH!!! Popcorn and remote in hand

Rihanna: @RobKardashian its past ur bedtime

Rob: @rihanna You can put me to bed ;)

Predictably, this exchange already has some gossip blogs conjecturing Rihanna is going to be Rob's date to sister Kim's upcoming wedding, which is ridiculous.

Interesting fact: even though it seems like Rihanna's been around forever and Rob has his whole little pal brother persona, Rob is actually a year older than Rihanna.
