"On my birthday I said 'yes' and 'forever' to the love of my life," she wrote.

"Chandler, close to 6 years ago I fell in love with you and every day since has been a whirlwind of adventure and true happiness. I'm so looking forwarding to spending our forever together as your wife. Here's to a lifetime of friendship, purpose and unconditional love. Now let's get married already!"

Chander, 22, also took to the social media website to announce the engagement.

"Almost 6 years ago we met at Australia Zoo," the pro wakeboarder wrote.

"I immediately fell head over heels for her kind and thoughtful heart that radiates so much light. Proposing in her very favorite place in the zoo, surrounded by animals, seemed like the perfect way to embark on this incredible new chapter in our lives. Bee, I love you more than anything in this world and I always will. Happy Birthday."

The star explained that her ring consists of a lab-grown diamond and recycled, rose gold metal - an appropriately eco-friendly choice for a young woman who has dedicated her life to animals.

"Chandler was incredibly thoughtful when he chose it," she explained on Instagram. "The ring captures the essence of who I am (with its vintage flare) and our life together, with the twisted band and scattered diamonds."
