Nicole Scherzinger is lazy about removing her make-up.

The 'X Factor' judge has confessed her worst beauty habit is falling asleep with a fully made-up face after a big night out.

She joked to heat magazine: ''I go to bed with my make-up on. Mostly after I've been out, if I'm tired. I find time to eat the Taco Bell, but not to wash my face!''

The former Pussycat Dolls star has had her fair share of fashion fails in the past, revealing the streaky blonde highlights she sported in the early days of her career couldn't have been further from her intention of emulating her pop idol, Jennifer Lopez.

She said: ''I wanted to be J-Lo when I was younger, so I dyed my hair blonde with streaks, but it looked green like puke. Then I had porcupine curls, as I call them, because my hair was unhealthy and breaking.''

Nowadays, Nicole focuses on keeping her long locks in good condition and says her go-to look is loose, tumbling waves.

She explained: ''Hair that looks gorgeous and effortless, that you want to put your fingers through. Not too much product. You want body and volume, but also bounce.''

However, the sexy star insists she would never wear hair extensions, scoffing, ''Never. I'm a real girl.''
