The 30-year-old model posted a sweet selfie of the pair on her Instagram account.
"A boat tour guide took us to a little spot on the lake and told us to make a wish. I asked for this to be the man I marry and have children with. I think John asked for the most perfect bite of cacio e pepe. Both came true, and here we are."
Chrissy and John met on the set of his 2007 music video for "Stereo," where he cast her after a mutual friend suggested they’d be great together.
"The shoot was pretty up close and personal, and I got to know her big personality—she’s very fun, very clever, very gregarious,” John recalls. “It’s not the normal way to court someone, but hey, it worked."
John popped the question during a holiday in the Maldives in December 2011 and the rest, as they say, is history.
