The newlyweds looked so in love while walking the red carpet together.
ET's Nischelle Turner caught up with the X-Men film's leading lady, who couldn't help but gush about how comforting it was to have him as her date.
"It's great. It's wonderful. It's nerve wrecking, but it's amazing [to have him here]," Turner expressed. "It's a bit of comfort in an otherwise nerve-wrecking day."
The newlyweds looked picture perfect posing on the red carpet. The blonde beauty was stunning in a black-and-gray striped strapless dress by Louis Vuitton that featured silver detailing and a black belt. She also wore earrings and a ring from the French designer.
Jonas, on his end, coordinated with his lady love, wearing a black suit with a black-and-white stripped shirt.
The night before, Turner dazzled in a silver metallic number while attending the Los Angeles premiere of Jonas' Chasing Happiness. ET caught up with the Jonas Brothers during the event, where they praised their wives for supporting them for the special event.
"It's a dream come true," Nick Jonas expressed. "They're all so busy that the fact that they get to come here and support us means the world."
