'He's a risk taker': Chloë Moretz on rumoured boyfriend Brooklyn Beckham
Now, Kick-Ass actress Chloë, 17, has spoken about her friendship with David and Victoria Beckham’s 15-year-old son.
"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!"

While Chloë first got to know Brooklyn in LA, she has many other famous British friends from her time living in London.
"I lived in London for so long when I was filming Hugo and Kick-Ass," the starlet said. "I've known Raff (Raffety Law, son of Jude Law and Sadie Frost) since I was like, 14.
"And Kiss-Ass screenwriter Jane Goldman's daughter Honey Ross is a good friend of mine too."
Chloë and Brooklyn certainly seem to be an athletic pair; they have also been seen enjoying several spin class dates at Soul Cycle in Brentwood.

"They cycle next to each other and are very cute," an onlooker told People. "Always look to be cheering each other on with smiles. They also both seem very competitive, but in a fun way.
"Brooklyn is always chaperoned by one of his parents. But both David and Victoria must be ok with Chloë, because they will chat briefly with her and then leave them alone."
