"Celebrating the goat and bringing back the red hair one last time," the actress, 33, captioned an Instagram post on Saturday, March 5.
In the fun photos from the night before, The Vampire Diaries alum and the 35-year-old snowboarder—once dubbed "The Flying Tomato," are seen partying with their loved ones at the Microsoft Lounge in Los Angeles.
In one standout snap, taken in a Pixster photo booth, White, Dobrev, and some friends wear long red wigs similar to the Olympian's signature hairdo in his younger years.
White announced his retirement plans before competing in the 2022 Winter Olympics last month in Beijing.
"This has all had its amazing glow to every single decision and every single competition because I've decided this will be my last Olympics," Shaun said during a press conference on February 5. "I've given it my all. There have been some ups and downs on the way to get here. But through all that, I feel I've got stronger and better."
Besides being the world's most decorated snowboarder with three Olympic gold medals, White also holds the record for the most medals won by an individual athlete at the Winter X Games, with 18 medals. Although he went home empty-handed from his fifth and final Olympics—placing 4th in his men's halfpipe final—Dobrev remained his biggest fan.
White and Dobrev have been dating for close to two years, and according to an insider, the pair is stronger than ever. They even openly talk about their future together.
