{blackbabes} Beyoncé Grows on Us, Sports Blond Bob With a Little Help From Her Extension Friends

Look who wanted to shake things up already!

A week after Beyoncé caused a small style earthquake when she showed off an impossibly chic blond pixie cut that took more than four hours to get just so, she's already sporting a new, longer 'do!

Today at lunch in Miami with hubby Jay-Z and daughter Blue Ivy, Mrs. Carter rocked a choppy, longer-in-front bob—with the help of some extensions, of course, so theoretically she can go back to the pixie at any time.

She's probably luxuriating in her fabulous short hair right now somewhere, in fact. But we understand why Bey may have been craving a little swing in her step—the 31-year-old singer had long hair for pretty much ever.

Anyway, she kept today's style in check with a gold headband (What, the tiara was at the jeweler's?) and looked every bit the superstar in short-shorts, aviator shades, oxfords and a loose tank-top that read "Name Brand."

But we do hope she hasn't already tired of the pixie. It's fab.

"I think it is sexy, strong, a statement, empowering," colorist Rita Hazan, who toiled for hours to give Beyoncé her new blond hue, told E! News. "She always had beautiful, gorgeous tons of hair and for her to strip down and reveal herself this way is a very powerful moment."
