Lily Allen is jealous of other female singers.

The outspoken pop star finds it difficult when she hears people getting excited about other women's music as she worries it means she will be forgotten.

She explained: "I get pangs of jealousy when I hear people like radio presenters getting really excited about new music. I kind of feel like, 'Oh, I'm just fading.'

"I don't feel I am in competition with all the other girls. I really feel this is the year of the girl, with La Roux and Little Boots and Florence Welch of Florence and the Machine.

"Who I really love is La Roux. She's a friend as well. I find it quite difficult getting on with a lot of my female competitors but I really, really like her."

Despite releasing her first single in 2006 and enjoying both critical and commercial success, Lily claims she still struggles with fame.

The 24-year-old singer finds it hard to deal with strangers on a daily basis because she doesn't want to disappoint them.

Lily - who has clashed with paparazzi on several occasions - told Britain's Elle magazine "I get quite shy and embarrassed, actually. I get embarrassed when people come up and ask for autographs. I find it odd when people say, 'Can I have your autograph?' because, why do you want my autograph? I really can't figure it out.

"I think people expect you to have a certain sense of decorum, but I almost find it like being a nursery teacher, having to be nice to people all the time. I haven't got a problem with that, but I think people expect you to know how to deal with s**t."
