To take time to recover, she is not going to do her show on Saturday in Wallingford.
She will do a show at Mohegan Sun, but not on Jan. 18. That date will be announced later.
Gaga tweeted about her ordeal on Thursday night.
I've been crying for hours, I feel like I let my fans down 2nite. An hour before the show, I was feeling dizzy and having trouble breathing, Gaga tweeted yesterday.
Later, she tweeted:
I hope you can forgive me. I love my little monsters more than anything, you are everything to me. I will make-up the performance on Jan 26.
Which show she is referring to, it does not say, but it's likely the Indiana show.
Live Nation says ticket holders will get refunds.
