R&B singer Toni Braxton was admitted to Hospital on Monday (April 9th) suffering from chest pains.

Braxton, whose hits include ‘Un-break My Heart’, was forced to cancel a concert in Las Vegas last night in order to undergo further tests.

A spokeswoman for Flamingo Las Vegas hotel-casino, where Braxton is currently performing, said the singer has been treated in the past for pericarditis, which is a viral infection of the heart.

Braxton is due to perform tonight (April 9th), although it’s not clear whether the concert will go ahead.

The singer began her two year residency at the hotel in 2006.
