Following her recent hospitalization, Toni Braxton is forced to scrap four more dates of her shows to give her time to recuperate. The multiple Grammy Awards-winning singer will not perform this week at Flamingo, Las Vegas where she serves long-running concert shows, but is expected to be well enough for a Tuesday, April 15 performance.

Deanna Pettit, a spokeswoman for the hotel-casino said on Wednesday, April 9, "We're going to go ahead and cancel her shows tonight and for the rest of the week. We expect she'll return to the stage next Tuesday." Pettit added that the singer is recovering at her home and refunds for the canceled shows are available.

Braxton, was admitted to hospital on Monday night, April 7 and was released a day after. There has been no statement from her rep regarding what causes the hospitalization but it has been known for sometime that she was once treated for pericarditis, a viral inflammation of the heart.

Braxton is performing six nights a week at Flamingo for "Toni Braxton: Revealed". Due to the success of the show, the contract has been extended up to August this year. She is also working on her sixth studio album which is slated for a release later this year.
