Keira Knightley's teeth are resilient enough to handle "life beyond romance."

The Pride & Prejudice actress surprised Cher by spontaneously singing a version of the singer's iconic song "Believe." She did this unique performance by tapping her teeth with her nails! This happened during a recent episode of The Graham Norton Show.

"This feels a bit like a dream gone wrong," Knightley remarked before belting out a version of the hit from 1998 while sitting on the studio couch alongside its original artist.

Cher appeared to be amazed by Knightley's unique ability. "You're nailing those notes!" she said excitedly. "You really hit them! How do you even know what you're—"

"I really can’t say why," Knightley replied, sharing that she discovered this unique talent during her childhood. "I picked it up when I was young. There was this popular kid at school who could do it, so we all wanted to try it too."

Norton commented that her performance lacks practical use in everyday life. "It's really impressive... but ultimately meaningless," he stated.
