Victoria Beckham has a posh new 'do!

On Friday, the star mom of four stepped out in Los Angeles to debut her new, shoulder-grazing haircut.

The long bob (which was dubbed "the lob" last year) is several inches shorter than the lengthy locks she was sporting before.

"Chopped it off! X vb," the 37-year-old proudly declared via Twitter Friday with a pic of her chopped-off ends.

Through the years, Beckham has undergone quite the conservative hair evolution. Once famous for her edgy platinum blonde inverted bob, she resorted back to her darker hair color at the end of 2007 and has been growing it out since.
