Australian rapper Iggy Azalea lost her virginity in her early teens after discovering she had an obsession with clubbers.

The pale star, who grew up in sheltered Mullumbimby, near Sydney, has revealed she used fake identification to get into city clubs - and she became hooked on seducing older boys, lying about her age and having sex with them.

The 23 year old tells Complex magazine, "When I was 13, I got a fake Id. I'd go out, get hammered off my face in nightclubs because I thought that made me an adult, meet older guys who thought I was older, and go f**k them. I'd do that all the time."

But one trip to a club made Azalea, real name Amethyst Amelia Kelly, rethink her late-night party lifestyle when a creepy guy followed her home.

She recalls, "He followed us through all the (train) carriages. Every station, we'd get out and switch a carriage and he would find the carriage we were in.

"When we got to the station in Sydney he started to chase us and was like, 'Come here, you little s**ts!' We ran and locked ourselves in a disabled bathroom and we stayed in there for, like, four hours until the sun came up and people were out for work again.

"That's the only time I've ever felt scared doing something dumb."
