instagram Now this gal is looking sinfully good!
Gorgeous Jessica Alba took a lighter approach to life by debuting a new blond 'do over the weekend.
And it was all in the name of work: The 31-year-old is currently prepping for her role as stripper Nancy Callahan in the highly anticipated sequel to 2005's Sin City.
It's not the first time the actress has rocked a lighter 'do for a role: She flashed fabulously blond locks for her roles in 2005's Fantastic Four and its 2007 sequel.
So, do blondes really have more fun? Well, this one certainly is: She had blast tweeting about her transformation, filling everybody in on each stage of the process.
"Bye Bye Brown Hair r u on viddy yet? I'm documenting my brown to Sin City blonde!" she tweeted on Thursday and included a link to a video showing her last hurrah as a brunette.
She followed that up with "Stage 1 -ok it doesn't look that different but it's a process" and snapped a pic of her sporting sexy tousled hair that indeed didn't look too far off from her original shade.
Patience, people, patience!
