In the wake of Toni Braxton's undisclosed illness, her show at the Flamingo Las Vegas has been canceled throughout the month of April, according to the Associated Press.

Braxton was hospitalized for chest pain on April 7. She was released the following day, but her show "Toni Braxton: Revealed" was cancelled throughout the rest of the week.

Flamingo President Don Marrandino announced yesterday that her Tuesday-through-Saturday shows will be dark throughout the month while Braxton takes advantage of a previously scheduled two-week break. Her return to the Flamingo Showroom is scheduled for May 6.

The exact cause of Braxton's chest pain has not been made public. She has been treated in the past for pericarditis, a viral inflammation of the heart.
