Perrie Edwards says she “wasn’t fit to perform” with Little Mix after being taken to hospital.
Jesy, Jade and Leigh-Anne had to go on stage at the iHeart Festival in Las Vegas without her on Saturday after she fell ill.
A statement from the band said she was forced to go to hospital because of a “gastric problem”.
She’s now messaged fans to tell them she’s “on the mend” and thanked them for their support.
In the message on Twitter, she says: ”Hello beautiful babas… I’m out of hospital… in my own bed, and on the mend. Thanks to mother goose, nurse sam and doctor hatchi I should be fine in no time.”
She also says: ”Sorry to have let you all down, I obv would never want to miss anything but sometimes you have to listen to those who know best and I wasn’t fit to perform.”
Before the update, Little Mix fans had been sending lots of love on Twitter.
Perrie was seen at the event on Friday, posing alongside her band mates in an olive green jumpsuit.

”My babas I love you all to the moon ad back.”
