Kim isn't the only member of the Kardashian family who's been sharing her beauty secrets recently. The reality TV star's younger sister Khloe has also been talking hair, skincare and make up with Into The Gloss - and her favourite product is almost as surprising as Kim's love of greasy locks.
When it comes to keeping her skin smooth and film, Khloe's go-to brand is designed for mums-to-be.
"Kourtney got me into all these Mama Mio products that are all natural - I think she used them when she was breast-feeding," Khloe told the website.
"Their names are really cute - there is one that's called the Shrink to Fit Cellulite Smoother that I like. I use one of their other products called the Pregnancy Boob Tube every day. It's got avocado oil and shea butter so when your boobs are growing you don't get stretch marks. I like it though, because it tightens your neck, too. I've been using it everyday for a year. Now people always ask me, 'Why do you have this?' hinting as if I'm trying to have a baby, and I'm like, 'No, no. It's just because I f*ckin' like it'."
As well as her love for Tom Ford lipsticks and eyebrow pencils - "I always have Anastasia Beverly Hills Perfect Brow Pencil with me," - girls on the go will be able to identify with her other beauty obsession.
"It smells really fresh and good," Khloe added. "It's different from a dry shampoo - it's good when you have bigger, frizzier hair because it adds a sheen to it even though it's not as heavy as an oil."
Yep. Khloe's an expert.
