For a relative newcomer Teresa Palmer is working the big names on the red carpet.

Last night she wore an Emilio Pucci Spring 2011 dress to her “I Am Number Four” LA Premiere.

Whilst Dianna opted for elegance, Teresa showed off her sexy side wearing this black backless dress with a thigh-high slit.

With her hair swept to the side she didn’t over accessorize her embroidered and embellished dress, as she just added a Christian Louboutin Larissa sandals and a black clutch to complete her look.

I prefer her look over Dianna’s, but I do wish Teresa had pulled her hair back.
