Toni Braxton has cancelled her Las Vegas shows after being hospitalised with chest pains.

The UnBreak My Heart singer was due to perform her 'Toni Braxton: Revealed' show at the Flamingo Las Vegas hotel from Tuesday to Saturday but was forced to pull out after doctors told her she needs further medical tests.

While the exact cause of Toni's hospitalisation earlier this month has not yet been revealed, the 40-year-old Grammy award winner has previously suffered from Pericarditis - a viral inflammation of the heart.

As she already had a two-week break scheduled, Toni is not expected to return to the stage until May 6 at the earliest.

Don Marrandino, president of the Flamingo Las Vegas, is offering refunds to ticket holders for the cancelled shows.

In August 2007, reports emerged that Toni was suffering from breast cancer, but she was quick to deny the story, insisting: "My health is in great condition."
