(CBS) Blake Lively is known for her blonde hair, but now the "Gossip Girl" actress has gone red for a movie role. 

The star attended the TIME 100 Gala in New York, wearing a green Zuhair Murad dress, and turned heads on the red carpet with her new fiery hair color.

Pictures: Stars' dramatic makeovers

"It's for the film 'Hick,'" she told People magazine. "I thought [my character] needed red hair. It helps when you're playing a role, when I don't feel like myself. And I don't really feel like myself with red hair."

The actress' colorist Rona O'Connor dyed her hair about a month ago, the magazine reports.

Lively said the new look makes her feel like the title character out of Disney's "The Little Mermaid."

"I love it," she told People. "I feel like Ariel."
