Katy Perry debuted a bright blue hair color last week, a move that comes just weeks after the announcement of her split from Russell Brand. Did the break up spark the new ‘do? Find out after the jump. According to her stylist, Perry had been talking about going blue for a few weeks. Rita Hazan told Us Weekly:

 

“It was not an interim shade. She knew it wouldn’t be permanent — just another Katy Perry look!”

 

 

I hear she dyed it to match something of Russell’s that has been lacking attention since the split ;)
