Jennifer Lawrence thinks ''confidence'' is sexy.

The 25-year-old actress, who recently split from Coldplay frontman Chris Martin, believes you can only look good if you feel good.

Asked what makes a person beautiful, the 'Hunger Games' star said: ''Ultimately, it's confidence that makes someone sexy and beautiful... When you feel amazing, it really shows.''

But the Oscar winner admits she wouldn't be able to prepare for red carpet appearances without her ''pit crew''.

The Dior ambassador said: ''I think it's important to give a hairstylist and make-up artist enough time. I'm always doing the nails at the same time. My dad calls [the team] the 'pit crew.'

''I love mascara. And I swear by the pink Dior Addict lipstick in Smile. It's quick and easy to apply, in the spirit of 'I don't care, but don't I look amazing?' I really do feel that I can be myself with these products.''

But she is must more low-key when it comes to her skincare routine.

She said: ''I wash my face, then moisturise.''

Jennifer isn't a fan of social media, but insists she recognises its importance for her generation.

She explained to Us Weekly magazine: ''Even though I don't engage in social media, it's been a huge part of letting our generation realise that they have a voice and you can get it out to the world.''
