Bindi Irwin undergoes emergency surgery after showing signs of 'discomfort' and 'pain'

Robert Irwin revealed that sister Bindi Irwin's appendix ruptured, causing her to undergo emergency surgery ahead of the annual Steve Irwin Gala.

Christina Dugan Ramirez is an entertainment writer for Fox News Digital. 

"She's going to be OK, but surgery – out of all the things we were ready for, that was not one of them," Robert told People magazine at the event in Las Vegas. "She’s just come out the other side of endometriosis and now the appendix goes. Health is so important – it really is. Bindi has become an incredible advocate for women's health, particularly, and I think it’s really important to prioritize getting help."

"She came to Las Vegas and was ready to come to the gala, put on a brave face in a lot of discomfort and a lot of pain and said, 'Nope, I’m just going to tough it out, I’m going to go for it,'" he added. "But the surgeon said, 'No, your appendix is going. That thing’s gotta come out.' Health has to come first. She’s very sad. She’s devastated that she and Mom can’t be here, but I know she’ll make a speedy recovery."
