POP babe Rihanna is dressed to paint the town RED as she enjoys a wild night out.

The boozy star, 24, danced the night away in a stunning red dress at the 1 OAK nightspot in Las Vegas.
Clubbers claimed she was sick at her VIP table. One said: “She threw up in a napkin. The guy with her handed her a white towel to clean up.”

But Rihanna was soon partying again, clutching her mobile phone and a drink and dancing with R&B star Ne-Yo.

She left the club at 5.30am but went on to the Spearmint Rhino strip venue.

Last week the Umbrella singer posted a picture of herself on Twitter with a topless stripper.
