Khloe Kardashian & Her Pregnancy Boob Tube Obsession

Keeping Up With The Kardashians' Khloe Kardashian is a self-described beauty addict and makeup expert. "I love doing my makeup - mostly because I'm pretty good at it," Kardashian told beauty blog Into The Gloss. Last week, Kardashian's half-sister, Kylie Jenner, sat down with Grazia UK to talk about her lipliner obsession and go-to drugstore beauty products, Us Weekly reported. During her interview with Into The Gloss, Kardashian followed her younger sister's lead by revealing her own makeup tips and the surprising secret to her beauty routine: pregnancy products.

Kardashian told Into The Gloss she first got the idea to use maternity beauty products from her sister, Kourtney Kardashian, who shared some beauty secrets of her own with ITG back in 2013. "Kourtney got me into all these Mama Mio products that are all natural - I think she used them when she was breastfeeding," she said. "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 your don't get stretch marks," Kardashian said. "I like it though, because it tightens your neck, too." The Kardashians have never been shy about sharing their secrets for flawless hair and makeup, and frequently document some of their more bizarre beauty treatments and makeup routines on Instagram. Kardashian's sister Kim Kardashian has also met with ITG to describe her famously elaborate contouring method.

Some of Khloe Kardashian's other favorite products include Make Up For Ever Aqua Lip Waterproof Lipliner Pencils, Tom Ford Lipstick in Sable Smoke and Spanish Pink, Urban Decay Naked Illuminated Powder in Aura and Becca Shimmering Skin Perfector Pressed in Champagne Gold. "I'm powdering with Ben Nye Translucent Face Powder all the time," Kardashian said. "Even at a red light...definitely before I leave my car, too. I'm also very into putting sunscreen on my hands when I'm in the car-I don't want to get sunspots. I keep a bottle of Lancôme's formula in my glove box. I also like the Neutrogena Ultra Sheer Dry-Touch Sunscreen because it doesn't leave the film that others will, which greases up your car."
