Ansel Elgort didn't do much dancing in The Fault in Our Stars , but off screen, the 20-year-old actor is a trained dancer. He showed off his tap-dancing skills  on The Tonight Show Starring Jimmy Fallon, and now we have a look at how he sweeps his ballet-dancer girlfriend, Violetta Komyshan, off her feet. In a fashion ad campaign for Amanda Uprichard  that the couple did together last year, they illustrate their goofy and adorable chemistry with twists, turns, dips, and kisses. Though Ansel and Violetta have been relatively private about their relationship, they stepped out at Paris Fashion Week this week looking closer than ever . The duo started dating when they both attended Fiorello H. LaGuardia High School of Music & Art and Performing Arts in NYC — yes, the school from Fame — and are shaping up to be one of our favorite couples.
