Elizabeth Olsen has long admired Taylor Swift. Unfortunately, a recent awkward encounter between the two left Elizabeth Olsen feeling like she may have blown her chances to be one of Taylor Swift’s BFFs.

Elizabeth Olsen, who is the younger sister of Mary-Kate and Ashley Olsen, opened up about the encounter during an appearance on The Late Late Show With James Corden.

“I really love her, and earlier in my ballet class, I was doing a dance sequence to her music,” Elizabeth Olsen said of her idol. “I only listen to her music when I’m working out, which is a little too often because of Avengers. And I just talked at her for like a long time. I think I blew it because we didn’t exchange phone numbers or anything.”

“Who takes the most time in the makeup chair?” Corden asked.

“Thor,” she said of Chris Hemsworth’s hammer-slinging god character. “He’s got a lot of hair, and he’s got a lot of body to put makeup on. He’s got a far larger canvas than most people, I’d say.”
