Kat Dennings wowed at the world premiere of "Thor: The Dark World" in London last night (Oct. 22), giving the film's female star, Natalie Portman, a run for her money.
Dennings rocked a low-cut gown by Lanvin as she posed on the red carpet. The velvet and gold dress suited her old Hollywood style, which was accentuated with a bold red lip.
The 27-year-old actress was joined by co-stars Portman, Chris Hemsworth, Tom Hiddleston, Stellan Skarsgard and Idris Elba. (Quite the good looking bunch!)
