Bajan hitmaker Rihanna has teased fans by posting a slightly cryptic tweet about a new film project.

The 'Umbrella' sensation recently appeared in her first movie, 'Battleship', and has now taken to social networking site Twitter to tell her 19.7 million followers that she's on location in New Orleans working on something exciting:

"Movie time in N.O, all my fav comedians in 1 room! Pure laughs non phuckin stop."

Back in April, Rihanna revealed that she wanted to star in a comedy in the future and even admitted that her favourite funnyman was 'Knocked Up' actor Seth Rogen, and her tweet from earlier today suggests she may have signed up for a cameo in Rogen's forthcoming motion picture, 'The End Of The World'.

Today's (May 30) midweek chart update revealed that her latest single, 'Where Have You Been', has moved up a position to No.5 and her album 'Talk That Talk' has climbed 1 place to No.11.
