It was only a couple of weeks ago that she was admitted into hospital, reportedly for “exhaustion and dehydration” following a string of wild nights out.

But that's not stopping Rihanna going out and enjoying herself.

The R&B superstar was seen dancing the night away at the Roxbury night club in Hollywood earlier this week.

And she ensured she had a good time as she danced with her friends and carried a bottle of champagne in her hands.

The Barbadian beauty hit the town on the eve of her big screen debut in naval war film Battleship.

And Rihanna decided to prove her devotion to America as she dressed in a plethora of US-friendly gear.

However,after a brief stay in the undisclosed medical centre, she was discharged and allowed to fly back to her home in Los Angeles.

It came just days after the 24-year-old singer pulled out of a Saturday Night Live rehearsal due to her tiredness.

And she appears to have been burning the candle at both ends as she works hard in the recording studio and promoting her movie Battleship.

While she's also been seen partying in a number of locations in between her hectic schedule.
