Ashley Greene doesn't ask her 'Twilight' co-stars for red carpet fashion advice.

The actress - who portrays vampire Alice Cullen in the popular movie series - loves to be surprised by what her castmates are wearing when they arrive at the same events together and also keeps her outfits under wraps.

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.' "

The 24-year-old screen beauty - who is dating singer Joe Jonas - prefers to wear quite simple outfits and insists she doesn't ever take long to get ready, even if she is attending a major Hollywood event.

She added: "My style in a nutshell is anything by J. Mendel. I don't generally wear patterns.

"I don't take too long to get ready - I work with such a good team they've cut it down to one hour."
