On Thursday Kylie Jenner and boyfriend Tyga spent a rare day apart as she lunched with friends and he cruised around Los Angeles.

Kylie and some gal pals dined at Johnny Rockets, and the 18-year-old reality TV star wore a shockingly age-appropriate outfit. Well, not so much when it comes to the price though. The Adidas getup, which was designed in collaboration with Mary Katrantzuo, retails at over $400. So much for practicality!

In other news, a new report on HollywoodLife alleges that Tyga, 25, will only have sex with Kylie if she has a full face of makeup on. “Tyga only likes having sex with Kylie when she is completely made up, that is what turns him on when she has all of her makeup on,” a source tells the site. “He considers it the only option when they have sex. No makeup, no sex.”

Maybe it's because she still looks like a child when she's going au naturel? We kinda believe it!
