Drew Barrymore partook in a 'gross' act with her co-hosts on her talk show which shocked audience members.

On Tuesday's episode of her eponymous talk show, the 50-year-old actress surprised her audience when she suddenly took off her shoes and socks to 'test her theory.'

The trio said they wanted to 'check a box of cleanliness' during their Drew News segment of The Drew Barrymore Show. 

And while discussing foot care, Barrymore insisted her feet don't have a smell and had her co-hosts to help her confirm if she was right.

That was when the actress stuck her feet up in the air for her co-hosts Sunny Anderson and Ross Matthew to smell.

This comes after Barrymore and Martha Stewart hashed out their 'beef' on air after the Charlie's Angels star revealed she has been told multiple times to 'back off' with her physicality.

While on air, Anderson recalled how she was once in a situation last year where she sniffed Barrymore's feet and told her they smelled 'divine.'

She also referenced a report from foot care experts 'begging people to prioritize washing their feet.' 

Matthews added: 'Drew does not have stinky feet. She's like a smell-good girl.' 

'It smells like a whole lot of nothing,' Anderson said. 'There's no scent there whatsoever. And believe me, I have other issues. Nobody escapes issues.' 

During their discussion, they also asked the audience about why they do or don't wash their feet based on a 2019 Self magazine report. 

The co-hosts asked their audience members to vote and shared the results afterwards, explaining that 87 percent of viewers in the crowd said they wash their feet daily. 

The rest of them included the 10 percent that said they wash their feet once a week, one percent said they wash them every month and the remaining two percent said they never wash their feet. 

Barrymore asked her audience members who voted in the latter two percent to explain why they opt out of washing their feet.

In response to a woman defending her choice, Barrymore quipped: 'I have a shower and the few times I tried to put soap on my feet, I almost died and slipped and fell.' 

Barrymore is no stranger to showing off her feet as she also took off her shoes once while taping The Late Show with Stephen Colbert in 2019. 

At the time, she told Colbert that she had a talent of 'picking up stuff with my feet.' 

She also called her foot her 'extra hand' for her to use. 

At the hilarious revelation, Colbert threw some cough drops on the ground, and the pair both removed their shoes to try and pick them back up. 

The mother-of-two said it was useful 'especially when you have kids.' 

The actress — who shares daughters Olive, 13, and Frankie, 11, with her ex-husband Will Kopelman — added: 'You know, you've got a kid in one hand and a phone in the other, there's no way you're not gonna go and grab that Ricola [with your foot]. 

'They're just when I need an extra hand,' she joked.
