Bob Irwin, the father of late conservationist Steve Irwin, says he hasn't been invited to his granddaughter's wedding.
The 80-year-old has been estranged from his daughter-in-law Terri and grandchildren, Bindi, 21, and Robert, 15, since he left Australia Zoo in 2008.
Irwin says he hasn't seen or spoken to his grandchildren for over 10 years.

In an interview with the Queensland publication the Courier Mail, Irwin says he has not received an invitation to his granddaughter's impending marriage to long-term partner, Chandler Powell.
"I haven't had an invite to the wedding and, to be perfectly honest, I wouldn't expect to be invited," he told the publication.
However, the grandfather says he wouldn't hesitate to accept an invitation if he were to receive one.
He reportedly sent a congratulatory letter to the couple, but has yet to hear back.
Irwin and his wife, Judy, wish the couple the best.
"Much the same as any other parent or grandparent, I would wish [Bindi and Chandler] the best - which I do," he said.
"Although a lot of untruths and rubbish and absolute garbage have been written in the past, you reach a point where you've had enough."
Irwin's estrangement from his son's family was highly-publicised following his resignation from Australia Zoo in 2008. His departure was caused by conflict with his daughter-in-law and Steve's close friend, Wes Carrion, over the operation of the Queensland attraction.
Irwin and his late wife Lyn founded Beerwah Reptile Park in 1970. They transformed the wildlife park into the internationally recognised Australia Zoo in 1992.
He told the Courier Mail he has not set foot in the zoo since his resignation 11 years ago.
"When my dad passed away, he [Bob] chose to distance himself from everything dad loved the most," Bindi Irwin said about her grandfather in a 2015 interview with New Idea.
"He hasn't had anything to do with us for a long time and he decided his own path... that's important, so good for him."
Bindi and her long-term partner announced their engagement on July 24 this year, on her 21st birthday.
The ceremony is expected to take place at Australia Zoo in 2020. Bindi reportedly plans to be accompanied down the aisle with her 15-year-old brother Robert, in place of her late father and distant grandfather.
