Chloe Moretz Invites Brooklyn Beckham To If I Stay Premiere

Chloe Moretz has reportedly been dating Victoria and David Beckham's son Brooklyn for three months. On Wednesday night, the 17-year-old actress invited her rumoured boyfriend to the premiere of her latest film If I Stay in Los Angeles.

Although Moretz and 15-year-old Brooklyn didn't pose together, his presence at the Hollywood event is a sign that their relationship is blossoming.

Both teenagers dressed up for the occasion too. Chloe chose a gown by Italian label Schiaparelli paired with a diamond bracelet by Van Cleef & Arpels.

Brooklyn teamed his navy suit with a grey t-shirt, trainers and the obligatory Hollywood staple - sunglasses.

Whether they're a couple or not, Chloe is enjoying spending time with Brooklyn during his summer holiday in LA. And when they're not attending swanky red carpet events, the pair are probably skateboarding or taking a spinning class.

"I don't know. I mean, he has a pretty small skateboard, and I like more of a long board," Chloe said in her recent interview with Company magazine.

"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."

According to People, the couple have also been spotted at celebrity fitness hangout SoulCycle.

"They cycle together and are very cute. Always look to be cheering each other on with smiles. They also seem very competitive, but in a fun way," a source said.

Aaahhh. Young love!
