Lucy Liu took nudes of Drew Barrymore on Charlie's Angels set and still has them today

Lucy Liu recently sat down with her former co-star on The Drew Barrymore Show to explain how she's still kept her backstage nudes from the Charlie's Angels set.

Just thought I'd remind you that Charlie's Angels came out 20 years ago - incase you want to feel old.

The action comedy famously stars Cameron Diaz, Drew Barrymore, and Lucy Liu as three women working in a private detective agency in Los Angeles.

Based on the original '70s series, the trio of elite private investigators work for unseen millionaire, Charlie Townsend (John Forsythe).

Fast forward two decades, co-star Lui, 54, - who hasn't aged a day - was a special guest on Barrymore's CBS show, which started off on a bit of weird anecdote.

"Do you know what I was actually trying to find?" asked host Barrymore, 48.

"I was trying to find the nude photographs you took of me on the set of 'Charlie's' in my dressing room."

"I have them," Liu responded straight-faced.

"And you look gorgeous, as you still do. And you're so natural and, you know, playful and having a great time.

"I have a series of portraits of so many people with and without clothes on, guys."

Later on in the candid interview, Barrymore asked her friend if anything in particular stood out from filming the 2000 movie, to which Liu simply recalled, 'pain'.

"I remember that they had to connect our legs to a wire to hold them up like that because it's impossible," she explained, while describing an old photo of the trio taken on set.

"You have to slant your body over. I'm kind of remembering, did we have to scale that fence also?

"In heels. But what a memorable photo it made, right? We were pretty badass. I remember eight hours a day of training, five days a week."

Lui also recently cleared up the idea that the film's three stars didn't get along.

"What I love about that relationship is that so many people denied it and created these rumors that we were fighting and that we didn't get along," she told People.

"But ultimately what I think people miss is that women can get along.

"We don't have to continue the idea that women are cat-fighting.

"And now we see with the #MeToo movement all of these things happening, and it sort of breaks and shatters those old prejudices."
