Rihanna cancels upcoming comeback gig

Rihanna has cancelled her first public performance since she was allegedly attacked by former boyfriend Chris Brown earlier this year.

According to The Sun, the 'Disturbia' star had been scheduled to play to 25,000 people in Dubai on May 28 but pulled out because she was not ready to return to the stage.

"We want to share with you that Rihanna and her management will not be accepting to hold a public concert at this time as it is not appropriate timing for her," said concert organiser Yassin Matbouly.

Last night, the singer made her first major public appearance since the alleged altercation, walking the red carpet at the Costume Institute Of The Metropolitan Museum Gala in New York.

Brown, 20, has pleaded not guilty to charges of assault and making criminal threats. He is due in court for a preliminary hearing later this month.
