Brie Larson on 'Wild' Premiere of 'Avengers: Endgame' & How '13 Going on 30' Impacted Her Career (Exclusive)

The actress also shared how excited she was to finally get to see the completed film.

Brie Larson slayed at the star-studded premiere of Avengers: Endgame in Los Angeles, California, on Monday.

The 29-year-old actress stunned while posing on the purple carpet in a plunging, Celine by Hedi Slimane gown with a leg-baring slit.

“It’s wild,” Larson told ET’s Kevin Frazier about experiencing the press tour and premiere with her castmates at the Los Angeles Convention Center. “There’s nothing like it. There’s no movie like it.”

To fans’ delight, the blonde beauty accessorized by wearing the infinity rings from the film franchise, gems representing such things as mind and power. Jeweler, Irene Neuwirth, shared how she was commissioned to create the jewels for Larson for the event.

Larson also wore opal earrings, diamond studs and a bracelet by Irene Neuwirth Jewels.

The actress plays Carol Danvers in Avengers: Endgame, which hits theaters on Apr. 26, and said she was thrilled to finally get to see the film.

“It’s been years,” she said. “I don’t know what the movie is. I have no idea what’s going to happen, so I’m excited to see it.”

The star also reminisced starring alongside Jennifer Garner on 13 Going on 30, which marks it’s 15th anniversary on Tuesday.

“I remember it was like the moment when I realized that I really wanted to direct,” she shared. “I remember paying a lot of attention to where the camera was and the camera moves, thinking about how I would have cut it together and then seeing the movie and seeing how it differed from what I thought.”

Since then, Larson has become quite the style icon and even had the chance to share some tips with Oprah Winfrey, giving her a lesson in perfecting the French tuck, made famous by Queer Eye's Tan France.

“I can’t believe I had the opportunity to teach Oprah the French tuck,” she admitted. “I mean really it’s Tan. Tan is the one who brought it all to the table, so I’m just happy to be able to share his work.”
