Chloe Grace Moretz says British men are like ''cobras'' and hide their true selves.

The 17-year-old star is said to be dating Brooklyn Beckham, and she has insisted while American ''boys'' are more bold and open, UK men are harder to read.

She told Yahoo!: ''UK boys are way more dangerous because they seem really nice and then it's like a sneak attack. They're cobras.

''You meet them and they're really quiet but secretly they're really crazy. American guys are 'I'm really crazy' or 'I'm really aggressive; and you see it, but with Brits you've got to figure it out.

''It's kind of scary. With Americans it's all out there, they'e like 'well there's my book, read it.' ''

Meanwhile, Chloe also admitted her movie roles have been inspired by her own love life.

She recently said: ''''Everyone says you have to draw from a modicum of self-experience for a role - love, in particular, when you're creating a love story.

''Not every relationship is the same, not every love that find is the same.

''Every kind that you get from another person - there are different types of it, and you learn through each relationship there are many different ways you can love someone.''
