The couple attended weekend number 2 of the festival, which wrapped up this past weekend. In Coachella.
The Vampire Diaries star donned a bright blue shirt which she wore unbuttoned over a white t-shirt with matching blue pants.
Later in the night, the two were spotted getting drinks at the bar as Shaun took a call on his cellphone and Nina held her boyfriend's white jacket.
Last month, Shaun and Nina, who have been dating for two years, enjoyed a tropical vacation in Costa Rica to celebrate the star athlete's retirement from professional snowboarding after dominating the sport for almost two decades.
