Drew Barrymore got up close and very personal with her Instagram followers with a beauty hack you have to see to believe.
The 50 First Dates star, 45, showed just how down-to-earth she is by posting a very messy video of her brushing her teeth, which included gargling, spitting, and even a bit of tongue scrubbing.
Drew shared the video as part of her Beauty Junkie Week series where she showcases her favourite products and beauty hacks too.

For this particular post, Drew tackled the problem of her teeth being too sensitive for bleaching, admitting she "can’t hack it" because it’s too painful.
The mum-of-two said she swears by a two-step formula by Crest instead and filmed herself scrubbing away at her pearly whites, while mocking herself along the way too.
"No wonder Crest isn’t calling me for an endorsement, with these teeth!" Drew laughed with a mouthful of toothpaste clearly visible. "I’m in on the joke."

She added: "Because I didn’t genetically get big, white fabulous horse teeth, we work with what we got."
Her fans couldn’t get enough of the video and commented: "I mean this with more love than I can bear - if you were any more down to earth you would literally be inner core."
Another wrote: "I can't believe I just watched you brush your teeth," while others marvelled at how "refreshing" and "charming" it is to see a celebrity without a perfect smile.
