Leonardo DiCaprio's girlfriend, Vittoria Ceretti, was spotted at the 2026 Oscars amid the actor's big night. DiCaprio, 51, walked the red carpet solo ahead of the Sunday, March 15, ceremony at the Dolby Theatre in Los Angeles. Meanwhile, Ceretti, 27, joined the One Battle After Another star inside the ceremony, marking the couple's first appearance together at an awards show since they started dating nearly three years ago. During Conan O'Brien's monologue, Cerretti could be spotted next to DiCaprio as the host made the actor into a new meme.
