The multi-hyphenate -- DJ, designer, singer, model, entrepreneur, heiress -- sat down with ET Style on the set of her new campaign in Hollywood as the newest investor in the Glam App, which connects you to makeup, hair and nail professionals for at-home services.
Since she was catapulted into fame in the early 2000s (the OG influencer, in our humble opinion), Hilton has been a beauty and fashion icon with her signature long blonde hair, smoky eyes and penchant for everything sparkly and pink.
Although she loves her blonde bombshell style -- "I love a cat eye, big lashes, lip gloss, bronzed and my blonde hair." -- Hilton is always down to experiment with different looks and has a vast wig collection to boot.
"I probably own like, 800 wigs," the "Best Friend's A**" singer told ET's Marisa Runyon.
"I have every single color, every style," Hilton continued. "I used to wear them to Disneyland and other places. If I'm ever in a certain country or I want to just like, go undercover, I'll just put on like, a short black wig and just go undercover and be in disguise."
There's no doubt former Simple Life star looks ageless. The 38-year-old credits her mom, Kathy, for paying attention to skincare at an early age.
"I'm all natural and I really thank my mother for that. She always taught me to stay out of the sun and to take really good care of my skin. I go once a week to Angela Nice and get facials and my favorite is her oxygen facial. And she also has another one called the red carpet facial. And then I get my Glam App done after and I'm just ready for a fun night out."
So what's the craziest beauty treatment she's received?
"I just tried the cryotherapy recently, and it was so cold like, literally it's like you feel like you're in Alaska. It's insane. I hope it works."
