LOUISVILLE, Ky. - Taylor Swift is postponing a show for the first time in her career.

Swift had to postpone Saturday night's sold-out show at the Yum Center in Louisville under doctor's orders because of an illness.

She tweeted the bad news to fans: "This is my first time having to do this. I'm so, so sorry."

Within 20 minutes hundreds of followers had responded with get-well wishes, which were already among the most popular international trends on Twitter for the day.

Swift postponed the show until Oct. 11. She's due for a short break before returning to the road in Charlotte, N.C., on Friday in support of her multi-platinum "Speak Now" album.
