Blake Lively (l. in Sept; r. on Tuesday) dyed her hair from blond to red for the movie 'Hitch.'

Blond be gone!

That's the choice Blake Lively made recently when it came to her flowing, golden locks.

The actress, well-known for her enviable sunny head of hair, showed off a shiny red 'do at the Time 100 Gala in Manhattan on Tuesday.

"She changed it for the film 'Hick,' which she is shooting now," her rep explained to the Daily News.

The film, which also stars Chloe Moretz, Eddie Redmayne and Alec Baldwin, is currently filming in Wilmington, N.C.

The new color isn't entirely a stretch for Lively since, as her rep pointed out, she went "brownish red" for the upcoming "Green Lanten" with Ryan Reynolds.

According to Movieline, more than a dozen shades were tested to get the right look for her character, Carol Ferris, though there is speculation that Lively ended up wearing a wig in the superhero flick.

The "Gossip Girl" star, 23, was recently named on the Time 100, the magazine's annual list of "the most influential people in the world."

Friend and director Baz Luhrmann praised the actress for symbolizing the "vitality of youth."

"That indefinable, natural, unprocessed glamour full of possibility and filled with anticipation for an endless future," he wrote in the mag.
