Bad hair day? More like bad hair week for Pink.

A couple days after debuting her new, grey-blonde pixie cut the L.A. premiere of The Lincoln Lawyer, the star fumed about her new 'do on Twitter.

"The woman that did my hair butchered it," Pink, 31, pregnant with her first child with hubby Carey Hart, tweeted March 13. "I hate it."

Several fans agreed. The pop star added, "Thanks for pointing out how much you all hate it, too. Helpful."
