Kate Winslet: 'I don't f**k around!'

Oscar-winning actress Kate Winslet opened up in a new interview, admitting she won't let anything get in the way of slowing down her career, not even her most current role as mum to her three children.

While the 38-year-old actress just gave birth to five-month old son Bear Blaze in December, she spoke to Harper's Bazaar and admitted: "It's time to get back."

She added: "Back to the 'I don't f**k around', back to the KW basics of take some serious risks, put yourself out there. And just really push it."

However, the Titanic actress has barely 'slowed down' after just filming her new sci-fi movie Divergent while being pregnant with Bear.

In fact, she's been so busy, she admits to barely having time to pamper herself and confessed: "I know it sounds very self-effacing because people say, 'Oh, you're a film star. People probably come to your house and do it.'"

She continued: "But I don't have the time to get my nails done apart from when I'm doing a photo shoot."

She revealed: "I'm quite excited about it actually. I really enjoy getting older. You just don't worry as much."

However, her carefree attitude may have something do with her current gig as the face of beauty giant Lancome.

She admitted: "Working with them does a huge amount of my self-esteem, I've got to tell you."
