Keira Knightley won't allow her daughters to use social media until they are 16

The movie star told The Independent: "At the moment, they're not allowed on any of it, which ... I don't know if that's right.

"If we can hold out until they're 16, then I will desperately try and do that. I've no idea if that's the right thing to do, or if we'll succeed in doing that."

Keira has often been paid less than her male counterparts. However, the actress also feels she's been "lucky" throughout her career.

She explained: "I know I've got [equal pay] a couple of times, and my agents have been very excited.

"You know, I'm incredibly lucky with the work that I do. I'm incredibly lucky with the money that I've managed to earn from it. I know I haven't earned anywhere near what my male counterparts have earned. I have nothing to complain about, equally, so I'm incredibly aware of how lucky I've been."

Meanwhile, Keira recently revealed that she's actively seeking new career challenges.

The actress - who enjoyed huge success with period dramas during her younger years - explained that she particularly enjoyed working on Black Doves, the spy action thriller series that also starred Ben Whishaw, and Sarah Lancashire.

Asked if she could be tempted back to period dramas, she recently told British Vogue: "I love that genre. I love history and trying to reimagine it. But, I have done a lot of them, so I don't like repeating myself. It has to be a character I haven't played before.

"Right now, I'm looking for stuff that's really entertaining, these proper genre thrillers, and that's what I've loved about Black Doves. It's like, you're going to come home from a difficult day at the office, make yourself a drink and just think, 'What's going to happen next?'"
