Kylie Jenner and Hailey Baldwin cruised over to Barneys New York in Beverly Hills on Tuesday to indulge in a little retail therapy, but interestingly enough, Hailey was the one behind the wheel of Kylie's velvet Mercedes SUV. What else are assistants best friends for?

Hailey flaunted her abs when she stepped out of the custom ride, and Kylie showed off her curves in a pair of skintight pants. However, when the ladies stopped by RH Modern in West Hollywood to check out home furnishings, Hailey seemed a little bit self-conscious about her sexy outfit, as she covered up her tummy with a jacket, grabbed her boob (?!) and flashed photographers a series of oddball faces.

In other news, Kylie has yet to comment on big brother Rob Kardashian's engagement to Blac Chyna, and when asked whether she's looking to get hitched to Tyga, she stayed mum on the matter. Tell us how you really feel, Kylizzle!
