Now, she has taken to Instagram to share a health update and thankfully she's on the road to recovery.
"On the mend", she captioned the black and white image.
At the time, Amy confirmed the scary news via a hospital bed selfie.
"Here’s what I’ve been up to this week. I was hospitalized for five days with a horrible kidney infection," she captioned an Instagram photo. "I wanted to share this with you because this is sexy as hell but mostly because I was meant to go to London for the opening of I Feel Prettyand my doctors have told me that’s a no go."
"I’m really disappointed selfishly to miss this trip because I love London and Europe in general and all the great people (food) there. But I need to put my health first," she continued. "I am so grateful for all the support the movie is getting. I hope people check it out in England and everywhere else in the world. It’s sweet and fun and you will walk out feeling better. Which is something I hope to feel soon too."
