Caprice would regularly down an entire bottle of vodka by herself and challenge men to boozy drinking contests at the height of her fame.
The former model and underwear entrepreneur confessed she used to get up to all sorts of "naughty" behaviour - including sex and drinking to excess.
"I never did drugs but boy did I drink! I'd drink a whole bottle of vodka on my own, easily. I'd drink every guy under the table. And I'd have competitions, too. I was hardcore," the now 47-year-old told New magazine.
"It was only when I went out and had a big night that I'd drink to excess. I'd never drink at home alone, ever. It was only when we were clubbing."
Angelina Jolie branded a 'horrible b****' and Brad Pitt 'an Aniston man' in rant
She refused to be drawn on her most embarrassing moments, only teasingly saying: "The things we'd get up to... yikes!"
Caprice, who is mum to sons Jax and Jett - one born via surrogate a few weeks before she gave birth - went on: "All I'll say is, it was naughty. It was crazy. We took it to the extreme. Sex, drink, all of it. It was over the top."
The former glamour model also branded Angelina Jolie a "horrible b***h" in the same interview, revealing she'd had dinner separately with her and Brad Pitt after his divorce from Jennifer Anison.
"She didn't say one word the entire night. She just sat there looking into space," Caprice said of the Maleficent star.
"Honestly, she was horrible."
Caprice - who has an estimated net worth of £23million thanks to her growing business empire - also claimed she invented the concept of the bargain, telling the mag: "When it comes to cleaning, I go to Poundland. I love it. And then Tesco for the toiletries, towels and stuff like that.
"I'm a businesswoman after all! My motto ism, why pay more when you can pay less? And with a family, things do become very expensive."
