She's an award-winning actress who could have a career as a musician if she wanted to, but that's just the tip of the iceberg when it comes to Keira Knightley's talents.

The English actress, who was just appointed Officer of the Order of the British Empire (OBE), recently showed off one of her more unique skills while appearing on the Graham Norton Show, and no one could've guessed it.

For the show's New Year's Eve "party pieces" segment, which encourages guests to show off their hidden party tricks, the Nutcracker and the Four Realms star surprised the every person in the room by doing something many people have never seen before.

While her fellow guests did impersonations of a baby crying and an opera singer, the mother of one offered to play a song using her teeth as a musical instrument.

"I can play my teeth! ... I can play anything you want," she excitedly told Norton,

Yes, seriously, Knightley flicked her finger nails against her teeth to deliver a rendition of Hal David and Burt Bacharach's 1969 hit, "Raindrops Keep Fallin' on My Head."

If you're having a hard time visualizing how playing a song with teeth works, here's the video of Knightley demonstrating her bizarre but amusing skill:

The Love Actually star also opened up receiving an OBE, and why it took her a few days to open the letter sent to her by the Home Office.

"I didn't open the envelope for about three days," she said. "It was from the Home Office and it was terrifying because I thought I was in trouble with tax and that I had messed it up and that they were going to take away the house. So, I hid the letter!"

She continued, "After three days, I thought, 'I am a mother. I am responsible, and I am going to confess to my husband that I've messed up,' So, I opened it, and it was a prize!"

Knightley's OBE ceremony was preceded by controversy after she criticized Kate Middleton's post-birth appearance. In an essay about her own pregnancy and birth experiences, the actress wrote that the fact that the Duchess of Cambridge "was out of hospital seven hours later with her face made up and high heels on," sends an unrealistic image to women.

"The face the world wants to see. Hide. Hide our pain, our bodies splitting, our breasts leaking, our hormones raging. Look beautiful, look stylish, don't show your battleground, Kate," she added.

While she denied shaming Kate, Knightley stood by her comments and won't apologize for her opinion,
