Bindi Irwin's younger brother Robert Irwin recently underwent an emergency appendectomy.

The 14-year-old Australian conservationist, photographer and television personality is the son of Terri Irwin and her late husband Steve, who starred in the popular docu-series "The Crocodile Hunter."

"Kicking off the new year with emergency surgery. I'm recovering well and feeling so much better without my pesky appendix!" Robert Irwin wrote Thursday in a message accompanying a photo of him smiling in a hospital bed.

Terri shared the same image on her Twitter account Friday, commenting: "The team at McKenzie-Willamette Hospital did a fantastic job removing Robert's pesky appendix on New Year's Day. #NationalThankYouDay."

An Australia Zoo spokesman told The Courier-Mail newspaper the youngest Irwin expects to return to work Saturday.
