Provocative: Rihanna posted this snap on her Twitter page captioned 'Come here Rude bwoy...'
She's just had a whirlwind trip tot the UK, making a showstopping appearance at the BRITs, celebrating her 24th birthday, and filming the Jonathan Ross Show.
And it seems all the excitement has finally caught up with Rihanna.
The 24-year-old tweeted a sultry shot of herself curled up on what looks like a hotel bed, captioned
'Come here Rude bwoy... '
The post was perhaps a cheeky reference to her cap, which had the word 'BOY written accross it in capitals.
Or maybe she was simply tired, as the star tweeted earlier today: 'Literally craawwwled to the plane! NO SLEEP!!! #AreWeThereYet'
