Jana Kramerwas forced to cut her opening set for Alan Jackson in West Palm Beach Friday night short due to dehydration and the flu.

After going fishing during the day on Friday with her boyfriend, singer Brantley Gilbert, she tweeted, " My how the day has changed. I am now sick with 101 fever and getting ready for this show is a challenge."

Kramer later tweeted that she "had no voice! Ill make it up to y'all I promise! Thanks for helping me thru this bug!"

On Saturday, Kramer tweeted, "I'm okay. I'm on morphine and lots of liquid and other stuff. #dehydration #flu #etc ! Thanks for the love!"

Kramer left the hospital hours later.
