Scarlett Johansson "offends" fans by refusing to take selfies with them

She told InStyle magazine: "It really offends a lot of people. It doesn't mean I'm not appreciative, of course, that people are fans, or happy to see me.

"But I always say to people: 'I'm not working.' I don't want to be identified as being in this time and place with you. I'm doing my own thing."

She added: "I like to be in my own thoughts that have nothing to do with what other people think of me. I don't like being self-conscious."

Scarlett went on to reveal she empathises with pop star Chappell Roan, who has been open about her struggle to deal with life in the spotlight.

She said: "Like everybody else, I fell in love with her over the summer. She's very outspoken about how hard it's been to adjust to fame.

"It's like heart-throbs. That's hard. When I was younger, I dated actors that had heart-throb status. That is, to me, scary. I don't have that level. Fan crush-dom can be really hard."

It comes after Scarlett admitted turning 40 in November has been a "liberating" experience because she cares less about other people's opinions of her.

During an appearance on 'LIVE with Kelly and Mark', Scarlett said: "So far, it's great ... You also don't care what anybody thinks, which is so liberating. It's so liberating!"

The 'Lost In Translation' star also revealed her husband Colin Jost threw a huge surprise party for her 40th birthday, saying: "He threw me a humungous bash this year. It was a surprise. And I had all the martinis for everyone and I can't wait to see the photos so I can remember the night ...

"It was magical. And he put it all together!"
