If you listen closely, you can hear Katy Perry's tired tresses crying out for mercy. On Monday, the doll-faced popster showed off a brand new marshmallow Peep-pink 'do while out and about in Los Angeles, her fourth hair hue in less than two months.
After spending part of June as a redhead (the color was an adorable accident as she lightened up her signature inky mane), Katy sported standard-issue blond locks at the July 24 premiere of "The Smurfs."
But she apparently ditched the lightened coif the next day, tweeting, "I have been dying my hair since 10pm! Good GOD let me get to my destination tonight! #beenblack #beenblue #beenhotginge #beenblonde #now... Still transitioning............... practicing patience!"
