Rihanna was taken to hospital following a concert in Switzerland on Monday night (April 19), it’s been reported.

The singer was apparently taken to a private clinic in Zuric just after midnight, where she was treated for an undisclosed condition.

The incident followed a sold-out performance at the Hallenstadion venue.

Alenka Ambroz, head of the clinic's corporate communications, said: "Rihanna arrived at the accident and emergency unit. We're not going to give any details."

According to The Sun, Rihanna left the hospital just over two-and-a-half hours after her admission.

She was well enough to continue her tour in Lyon, France last night (April 20).

Rihanna is due to begin the UK leg of her European jaunt in Birmingham on May 7.
