During a chat with E! News on Saturday, the "Roar" singer told them she would be changing her hair color to "slime green" on Sunday, which may or may not have been inspired by the Kids' Choice Awards.
"I've wanted to go slime green for a long time," she told them. "It's spring time and I think it's time to freshen up my look...I'm really excited about slime green, but I hope my hair doesn't fall out."
We don't know that "slime green" or lime green, for that matter, necessarily screams "fresh" but hey, if it makes her happy, slather on the slime.
Katy is fresh off of a break-up with on-again, off-again boyfriend John Mayer and they seem to be serious about their "off" status this time, so maybe she's doing the whole revenge makeover thing-- although usually you go platinum blonde or something to make your ex realize how hot you are.
We haven't seen a lot of hot girls rocking this particular hair color, but maybe Katy will start a new trend and John will realize just how badly he wants to run his fingers through her slime-colored strands. Maybe not.
No updates from Katy about whether or not she actually went through with the 'do, but we'll definitely keep you posted.
