Kim Kardashian spandex sunglasses gym clothes Blac Chyna

It's Kim Kardashian with ... Amanda Bynes' former style icon? Yet again, Kimmy K and Blac Chyna hung out, but their main men Kanye West and Tyga were nowhere to be seen. Maybe these two are really BFFs when the boys aren't around?

Kim and Blac Chyna got some beauty treatments done in Beverly Hills on Sunday, and on Friday the ladies went shopping together at Neiman Marcus in Topanga Canyon. Wonder if they ever swap style secrets?
