Chloe Grace Moretz and Brooklyn Beckham "chose each other"

She told Us Weekly magazine: "I think we chose each other. It's been years now off and on and it's just one of those things, you come back and it's like no time spent away from each other at all.

"I think that's the most important thing and you're lives are an open book. We like to have our own little private world and I think that's important for both of us."

And Chloe admitted she likes to "steal" her "adorable" boyfriend's clothes - but he swipes her beauty products.

She admitted: "We share a lot, well I share a lot of his clothes. Well, I steal a lot of his clothing. That's more the realistic thing here.

"I think he's adorable. I give him good facial products and I take his jackets!

"So he steals my facial products, I give him a good facial regime and I get to wear the jackets."

The 'If I Stay' actress doesn't care what they do on their date nights, just so long as they're together.

Asked her favourite date night, she said: "Just he and I together. Don't need much more than each other's company whenever we can grab it."

Chloe gets along "very, very well" with 18-year-old Brooklyn's famous parents, David and Victoria Beckham, but she admitted she was in awe of the former Spice Girls singer when they first met.

She gushed about the 43-year-old fashion designer: "I think if anyone didn't say that when they met her, that would be shocking.

"I think she's one of the most incredible, important, smart, sophisticated businesswomen and mothers that I've ever met. She's a real heart and a real beautiful person."
