Kristen Stewart has been an actress for pretty much forever and, having been ‘famous’ since the age of eight, we don’t blame her for not pandering to the paps. 

Researchers have used a machine to analyse facial expressions and what they found is, while the majority of people have neutral faces, those who've got RBFs (see Kanye, also), have higher levels of 'unconscious subtle contempt' that viewers can pick up on. So, it's just a roundabout way of saying they are actually disdainful, but not 100% on purpose.

Here’s why we rate K-Stew, RBF or not…

1)    She’s actually a pretty good sport, playing The Whisper Game with Jimmy Fallon.

2) She’s sassy as hell. One of her best moments was when she first got her hair cut into a crop and was asked why: ‘As soon as I didn't have all that hair, I had to let my face hang out. I felt more confident than I had in a really long time. It felt really good […] Maybe to most people long hair is prettier. But then what? […] Is your main goal in life to be desired? That is boring as f*ck.’

3) That time Those times she took her heels off on the red carpet and when she wore Vans for her star ceremony on the Hollywood Walk Of Fame. We wouldn’t choose to wear a heel so why we should expect slebs to wear them?!

4) She the best at the androgynous red carpet look; suits, tailoring – so hot right now.

5) What would she be doing if she wasn’t an actor? ‘Catering’, and not just usual catering; ‘'I really like cheeseburgers. And hot Cheetos’, she revealed during an episode of Carversations.

6) She’s actually a damn good and varied actor, having starred in everything from Twilight to Still Alice, the latest Chanel biopic Once And Forever and Sils Maria.

7) Considering she was a child star, acting in Panic Room at the age of 12, she’s really stayed firmly on the rails – something which she attributes to her family.

8) She was talent scouted at a school Chirstmas play aged 8. Beats an audition any day.

9) She’s hella modest, as winner of a fair few fancy accolades including a Young Artist Award, a César award (the only American to win apart from Adrien Brody), a 2010 BAFTA Rising Star Award and best actress at the Milan International Film Festival

10) The gal can sing! For her role as Joan Jett in The Runaways, she recorded the vocal for six songs used in the film and its soundtrack. She can also play the guitar and trumpet.

11) She gives one hell of an acceptance speech. When picking up her Orange Bafta, she said: ‘Wow. Thank you. I guess first I have to thank all the fans of Twilight for proving again and again to be THE most devoted and attentive fans ever. Considering this is voted, credit is due to them so thank you. To the other actors nominated, I am so blown away by you that I can't even describe it. To be voted among you is just overwhelming. And I'd like to say hi to my family.’

12) She isn’t one to talk about her relationships - FAR from it – though she’s talked about not wanting to talk about it: ‘I would never cheapen my relationship by talking about them. People say, "Just say who you're dating. Then people will stop being so ravenous about it." It's like "No they won't! They'll ask for specifics’. Another time, she said: ‘I wouldn't tell you anything about anybody I cared about because it becomes entertainment for other people, and it sort of just cheapens everything in your life. I would never tell you if I was dating anybody.’

13) She sure does make an excellent Chanel girl.

14) Sure, she’s not a smiler but she opens up about what it’s like to be famous, totally aware of how she comes across: ‘What you don't see are the cameras shoved in my face and the bizarre intrusive questions being asked, or the people falling over themselves, screaming and taunting to get a reaction.’

What a babe.
