Kendall Jenner and Kylie were closer than ever as they posed on the red carpet at their private lunch at Chateau Marmont on Thursday.

The Calvin Klein model, who wore a black and white gingham print bandeau with bow detail and matching pants was joined by her newly-blonde little sister Kylie as they promoted their joint fashion venture.

Kylie, 18, who is experimenting with the honey-hued locks, leaned on her sister Kendall as they posed for the camera, while rocking a form fitting dark grey mini-dress.
