Wedding Bells For Bindi & Mom Terri!

Croc Hunter’s widow & daughter marrying their men in romantic double ring ceremony

Crikey! Crocodile Hunter Steve Irwin’s beloved daughter Bindi is marrying her American boyfriend — and her mom, Terri, is getting in on the act by tying the knot with squeeze Russell Crowe in a double-barrel delight, sources tell GLOBE!

Although plans for the late February nuptials at the family’s Australia Zoo are still being developed, insiders say Bindi, Steve’s widow Terri and his pal Russell are intent on using the ceremony to honor the memory of the popular star, who was killed by a giant stingray in 2006 while filming a TV episode off Australia’s coast.

Bindi will pay tribute to her dad by wearing an emerald green dress while exchanging vows with Florida-born wake boarder Chandler Powell, 22!

“Steve loved the color green because it reminded him of wildlife and the crocodiles,” dishes an insider.
