Get Better Toni Braxton!

Toni Braxton is on the mend and in "good condition" following a health scare.

The 40-year-old "Un-Break My Heart" singer was admitted to Las Vegas' St. Rose Dominican Hospital for chest pains Monday night. 

The six-time Grammy winner, in Vegas headlining a five-nights-a-week show at the Flamingo Hotel and Casino, is currently listed in good condition and is expected to be released later Tuesday. 

But according to a Flamingo rep, Braxton won't be able to go on with her Revealed show right away.

"We wish Toni a quick recovery and would like her to take the time she needs to regain optimal health," 

said Don Marrandino, the resort's president . "We are looking forward to her return at the end of the week." 

The singer's agent at ICM, Mark Seigel, would not comment on Braxton's hospitalization. Though several reports have erroneously claimed that Braxton was taken to the hospital immediately after a performance, there was no Revealed scheduled for Monday. (The show is dark on Sundays and Mondays.) Hotel officials also clarified that Braxton was not at the casino at the time. 

While there hasn't been any further details released on her present ailment, Braxton has previously admitted suffering from a condition called pericarditis, an inflammation of the lining of the heart, which she was diagnosed with four years ago. 

In a January interview with Newsweek, Braxton said she periodically suffers from heart flutters and high blood pressure. 

Since her disclosure, Braxton has since been named a spokeswoman for the American Heart Association. 

Braxton's act, "Toni Braxton: Revealed," also has shows scheduled Thursday, Friday and Saturday in the vintage 720-seat Flamingo Showroom. Her two-year run at the Flamingo began in August 2006. Her run ends August 23rd. Donny and Marie Osmond take over in September.
