Ashley Greene only takes 15 minutes to get ready for a showbiz event.

The 'Twilight' star - who recently split up with boyfriend of nine months Joe Jonas - doesn't like to "fuss" about with her own look, but does enjoy getting pampered if other people are responsible for her make-up and outfit.

She said: "I love having my hair and make-up done, but I'm really just a 15-minute girl, throwing everything on with no fuss."

However, the same speedy process doesn't apply when she has to get into the character of vampire Alice Cullen in the 'Twilight Saga' movies.

She revealed to InStyle Hair magazine: "The whole process takes about two hours.

"My hair is pretty thick, and we wrap it and put it under a wig. To get it to fit so I don't like look I have an alien head is a talent in itself."

Earlier this year, the 24-year-old actress admitted she doesn't ask her 'Twilight' co-stars for red carpet fashion advice.

She said: "The 'Twilight' cast don't consult each other about red carpet looks, so it's a surprise on the night. We're like, 'Oh my God, I love your outfit.' "
