Perrie Edwards was absent from Little Mix's set at the iHeartRadio Festival on Saturday (Sept. 23) in Las Vegas, but she took to Twitter on Monday (Sept. 25) to assure everybody that she "should be fine in no time" after a short hospital stay.

"Hello beautiful babas...," she wrote in a note posted to Little Mix's official feed. "I'm out of the 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. 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. Thank you to the lovely doctors and nurses at sunrise hospital in Vegas for looking after me! My babas I love you all to the moon and back."

It was reportedly "gastric problems" that sent Edwards into hospital care as her Mix mates -- Jesy, Jade and Leigh-Anne -- soldiered on without her at the festival.

Edwards has also appeared in recent news after boyfriend and soccer star Alex Oxlade-Chamberlain transferred clubs from Arsenal to Liverpool as Edwards will remain in London. "We'll be fine," she told the Mirror. "I'm just really happy for him and very proud."
