The stunning model, who was rushed in to the hospital last night after, has thanked her fans for their "concern".
The 19-year-old star posted a snap sat in a wheelchair in a hospital gown looking sadly up at the camera.
"Appendicitis swag thanks for all of your concern," she posted on Twitter.
The pain comes after Ireland posted a cryptic message on April 1, appearing to signal she was in pain, saying, "I can't move."
But despite the pain, she has been promoting her latest lingerie shoot with as much enthusiasm as ever before her recent hospital scare.
