The pair, who have been spending lots of time together since they were spotted skateboarding together along Santa Monica beach in June, didn’t pose together for photographers on the red carpet.
Brooklyn, 15, looked dapper in a black T-shirt and navy suit with black lapels. A pair of Aviator sunglasses hung from his T-shirt, and he mixed up his outfit with a pair of brand new white trainers.
Seventeen-year-old Chloe dressed for the occasion in a Schiaparelli gown that was reminiscent of old Hollywood glamour.
The glamorous floor-length number featured a sheer black layer over a patterned blue material adorned with pink flowers motifs.
The actress wore natural make-up, with her blonde locks flowing loosely about her shoulders.
She kept her accessories to a minimum with just a delicate beaded bracelet by Van Cleef & Arpels.
The Kick-Ass actress recently spoke about the pair’s friendship.
“I don’t know!” she laughed when asked by Company magazine who is the better skateboarder. “I mean, he had a pretty small skateboard, and I had more of a long board.
“I think he’s a risk taker, like a typical guy, weaving in and out of people. I’m a ‘ safety boarder’ – I don’t want to break any bones!”
