Things aren't looking so pretty for Amy Schumer.

On Friday (April 27), the I Feel Pretty actress announced on Instagram that she's been in the hospital with a terrible kidney infection, resulting in the cancellation of her planned appearance at the upcoming London premiere of her new film.

"Here’s what I’ve been up to this week. I was hospitalized for five days with a horrible kidney infection," she wrote on Instagram alongside a photo of her in a hospital bed. "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 Pretty and 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."

This isn't the first time Schumer has been hospitalized and shared her experience on social media.

In September 2016, the comedian posted a video of herself in the hospital on Instagram, announcing she got food poisoning during a trip to Paris.
