According to Tulsa World, "Officials with Minnelli's management said Minnelli's doctor requested she cancel a series of shows to focus on improving her health."

"Liza Minnelli has been advised by her physician to cancel her upcoming concerts in Oklahoma and Texas. She deeply regrets that she will not be able to perform for her devoted fans and is very grateful for the love they have shown her throughout her career."

This is not the first time of recent that Minnelli's been forced to cancel shows. In May of last year, Minnelli pulled the plug on a July show at London's Royal Albert Hall in July, as well as three other dates in France and Holland.

No word has been given as to if or when the shows will be rescheduled.

Get well soon, Liza girl.
