The Food Network star's son, Ryder, 18, made a public display of affection for his girlfriend Sophie by resharing a romantic photo. Ryder reposted Sophie's Instagram Stories after she shared a sunset photo of the pair kissing on a boat in honor of National Boyfriend Day on Oct. 3.
"I love life with you," she wrote. Ryder captioned his repost with "I love you."
Ryder and Sophie attend San Diego State University together. Ryder "got into every school" he applied to, Guy told PEOPLE in May, but "the one that he was most interested in was San Diego State."
Before they headed off to college, the couple went to their senior prom together. Ryder shared sweet Instagram photos with Sophie and his group of guy friends before the big event. "Last one❤️📸." he said.
In March, the Diners, Drive-Ins and Dives star shared exactly how Ryder asked Sophie to the dance. While on a dinner date at Boon Eat + Drink in Guerneville, Calif., Ryder got a little help from the restaurant's owner-chef Crista Luedtke, who participated and won his dad's show Guy's Grocery Games.

Both of the Fieri boys are in serious relationships. Guy and his wife Lori's older son Hunter, 28, is engaged to Tara Bernstein. The two are set to tie the knot in 2025.
Hunter and Bernstein, a professional pickleball player, held a pickleball-themed engagement party in New York's Central Park on June 23 to celebrate their engagement.
For the party, the bride-to-be wore an all-white activewear minidress with a collared neck and pleated skirt. Hunter matched in a white short-sleeve button-down and white shorts. Meanwhile, guests were decked out in all-black outfits, which is typical of dad Guy's wardrobe anyway.
Guy shared some sweet sentiments at the party, according to videos recorded of his speech.
"I really don't have any expectation other than the universe, the world, is yours. You're going to do whatever you two want to do. I think that you'll have a great family. I think you're going to have successful careers. I think you're going to travel the world," said Guy. "I think you're going to own it."
