Keira Knightley has one very unique hidden talent.

With the coronavirus pandemic still underway, more and more celebs have joined together to celebrate frontline workers and promote positivity.

Lady Gaga, one of the event's curators, hosted the event for two hours.

"I care so much about the medical workers that are putting their lives at risk for us,” she said.

She lended her musical talents to perform Nat King Cole's version of the song “Smile.”

It was definitely the kind of positivity that fans needed!

The singer was joined by several big-names, including Stevie Wonder and Paul McCartney.

She even made a sign, which she proudly showed off.

"And I was trying to think of something entertaining to do and I couldn't think of anything, so I'm going to play my teeth," she said, smiling.

Calling it her "one and only party trick," the Love Actually actress brought her hands up to her mouth to play 'Yesterday' by the Beatles.

In case you don't know what "teeth singing" is, her teeth don't actually make noise on their own.

She uses her fingers to tap against her teeth to make the sound.

"Thank you very much for watching," she said with a big smile at the end.

She then sent out her thanks to all the frontline workers and medical teams who are doing everything they can in the fight against the coronavirus.

"If you want to donate, that you would be great," she said, before showing off another sign she made with the web address to donate written on there.

Keira's special talent got her lots of props from fans.

"Keira, you’re amazing! We love you," added another.

Turns out, this isn't the first time the actress has shown off her teeth-playing musical talent.

While on The Tonight Show Starring Jimmy Fallon last year, she performed ‘Despacito.'

She's one talented person!
