Kristen Wiig's Changing Looks

Subtle highlights for a Walk Hard: The Dewey Cox Story press conference.

For Time Magazine's 100 Most Influential People bash, the SNL star complemented her auburn hair with glossy red lips.

A side ponytail and a glowing complexion for the premiere of Ghost Town.

Wiig sported a wavy shoulder-length bob and baby-blond highlights.

She updated her cut with side-swept fringe.

For the Bridesmaids premiere, Wiig wore her ombre locks loose and played up her cheekbones with peach blush.

Wiig was a natural at the Golden Globes. "I wanted volume on the sides, but not on top, and a matte finish," hairstylist Mark Townsend said of the look. "I think that's so modern-this isn't a beachy wave. This is something new."

For the SAG Awards, Wiig wore her brunet strands in a low bun.

Wiig lightened her strands to a reddish-brown tone. "It's only a couple weeks old, so I'm getting used to it, but I like it," she told InStyle.com at the Elle Women in Hollywood celebration in Los Angeles. "It's for a film. I love it."

Tousled waves and mauve lipstick at the Golden Globes.

Wiig chopped her red hair into a blunt bob for The Spoils Of Babylon premiere.

Back to blonde! The actress showed off a new hue and a choppy short 'do at the premiere of Welcome To Me.

The Ghostbusters star looked gorgeous with slightly darker, shoulder-length tresses styled into loose beachy waves. She styled the cut in a deep side part at the premiere of her new film.
