Braxton's shows canceled until May

LAS VEGAS, April 14 (UPI) -- Toni Braxton's performances at the Flamingo in Las Vegas have been canceled for the rest of the month because the singer has been ill, the hotel said.

Representatives from the Flamingo told TMZ.com Braxton isn't expected to resume performing her show, "Revealed," until at least next month, so the singer can undergo more medical tests.

Braxton was hospitalized last week after experiencing chest pains.

The singer reportedly has a heart condition called pericarditis, which she found out about after giving birth to her second son.

Braxton is a spokeswoman for the American Heart Association
