Toni Braxton was rushed to St. Rose Dominican Hospital in Las Vegas on Monday night, April 7 after complaining of chest pains. The six-time Grammy winner is said to be on the mend and in "good condition" following the hospitalization thus is expected to be released from the hospital on Tuesday afternoon, April 8.

Braxton has been headlining her "Toni Braxton: Revealed" show at Las Vegas' The Flamingo since August 2006. She recently re-upped her contract to extend the five-night-a-week show through August. However, due to her hospitalization, the songbird won't be able to go on with her "Revealed" show right away, a Flamingo representative has stated.

And while the cause of the chest pains was not immediately known, it's been revealed that Braxton once was diagnosed with a heart condition called pericarditis, which is an inflammation of the lining of the heart. "We wish Toni a quick recovery and would like her to take the time she needs to regain optimal health," said Don Marrandino, president of Flamingo Las Vegas. "We are looking forward to her return at the end of the week."

Braxton's representatives and manager declined to comment on her ailment though.

Braxton reportedly found out that she suffered from pericarditis way back in 2003 after the birth of her son Diezel. Since her disclosure, she's been named a spokeswoman for the American Heart Association.

Concerning her hospitalization, Braxton has to unfortunately cancel her "Revealed" show for the time being, but fear not for the hotel was offering refunds to the canceled Tuesday show.
