Carey Mulligan ''used to freak out'' if she didn't have another acting job lined up.

The 'Great Gatsby' star admits she used to panic if she didn't know what acting job she was going onto next but there are more important things to her now.

She said: ''I used to freak out if I didn't have back-to-back work lined up.''

And the 33-year-old actress admits she ''sometimes feels like an imposter'' because she didn't go to drama school or university.

She added: ''Sometimes I felt like an imposter. I didn't get into drama school, I didn't go to university, so this was my homework ... I was a drama geek, I was most definitely not one of the cool girl.''

The blonde beauty's number one priority now is her two children, who she shares with her husband Marcus Mumford.

She shared to The Sunday Times' Style magazine: ''Now I have children I just don't have the time. I've run out of steam by 7.30 ... The first time I did press after I'd had my daughter, she was one month old. I literally ran to the red carpet, did it, ran home, pulled off my dress and fed her in my Spanx and 6in heels.''

Meanwhile, Carey previously confessed she used to cry after red carpet events.

She said: ''I hated all of it - the interviews, the red carpets. I used to get to the end of a red carpet and start crying - I felt so uncomfortable. It took a lot out of me and it was an alien environment that I felt completely out of kilter with. These days it's all fun, that's the only way to take it. Something like that would never scare me now in the way it did then.''
