Cara Delevingne wants to be an ''astronaut or a spy''.

The 24-year-old model-and-actress would have taken her life in a very different direction if she hadn't found success on the catwalk at a young age.

She said: ''If I hadn't gone into modelling or acting, I would have loved to be an astronaut or a spy.''

The 'Paper Towns' actress is known for her bushy brows, and though she didn't like them when she was younger, she's learned to ''embrace'' them and is thankful she followed the advice of her mother not to pluck them.

She said: ''The best beauty advice I've been given is from my mother, who told me not to pluck my eyebrows...

''All the women in my family have really big brows. As a child, I didn't care for mine, but I've since learned to embrace them, as you should. Now, I keep them in check.''

When she is acting, Cara relies on make-up to help her get into character.

She explained: ''Make-up really helps me get into character for my acting roles.

''It's like putting on another skin, another armour, which helps me transform into any character.''

But if she has a day off, Cara prefers to go bare-faced.

She told Britain's ELLE magazine: ''On my days off, I like to keep things simple and let my skin breathe, so I'll go make-up free.

''I always keep a mascara in my bag for when I need to quickly turn things around from day to night.

''Rimmel Scandaleyes Reloaded Mascara is my trusted favourite.''

The blonde beauty isn't a fan of working out regularly but does try to stay active.

She said: ''My approach to working out is sporadic. But I like going to boxing and dancing classes. It's good to keep moving any time you can.''
