British singer Lily Allen has a fear of being booed on stage - because she believes that she is the "uncoolest" person on earth.

Even though she has never been booed on stage, the 22-year-old Smile hit maker puts the strange phobia down to growing up in the shadow of her famous father, actor Keith Allen.

"I actually do really believe that people hate me and whenever someone introduces me on stage and they go, 'Now, Lilly Allen,' I wait for people to start booing," Contactmusic quoted her as saying.

"I think I'm possibly the uncoolest, naffest person ever to walk the earth. I've felt like that since I was a kid. It's less so now but I do definitely get that feeling specifically when people introduce me.

"I grew up my whole life in my father's shadow. I wanted to be Lily Allen, not just Keith's daughter," she added.

Meanwhile, the pop star has announced that she may retire from the music industry before she turns 25, and lead the life of an ordinary person.
