The model and R&B star have two reasons to celebrate on 14 September - it marks the day they met on the set of John's Stereo music video in 2007, and it's also the date they tied the knot during a romantic ceremony in Lake Como, Italy in 2013.
And on Wednesday (14Sep16), Chrissy acknowledged the big day on the popular app, sharing a video of her saying, "10 years ago, I met the best man on this planet."
She then planted a loving kiss on her husband's lips, saying, "I love you. Happy anniversary."
And for the first time within the timeline of their lengthy relationship, the couple gets to celebrate with its five-month-old daughter Luna, who Chrissy also featured in her snaps, by posing with the tot using various filters, including a butterfly crown and matching deer masks.
The lovebirds are celebrating their anniversary in New York City, where the Sports Illustrated beauty has been documenting her New York Fashion Week adventures on Snapchat over the past few days.
In a series of hilarious videos, Chrissy acted as a roving reporter at the annual event, pretending to chase down Kendall Jenner, who turned out to be a painting of a woman on a wall mural. She also bragged about getting into the "hottest parties" before revealing she stood in front of convenience store 7-Eleven for a Buy One, Get One free special, and the goofy supermodel also took a behind-the-scenes look at how she preps for a fashion show by laying on a couch and only wearing a towel.
She lazily says, "Hey guys, Chrissy Teigen here and the stars are out in full force. Let's Go to Michael Kors!", before rolling off the couch and falling hard on the floor.
Meanwhile, John just joined his wife in the Big Apple, after appearing on the red carpet for the premiere of his new film La La Land at the Toronto Film Festival on Monday (12Sep16).
The singer stars in the buzzed-about movie alongside Ryan Gosling and Emma Stone, and also serves as an executive producer.
