The 'Teenage Dream' singer confirms she has adopted a new look but has yet to reveal her new hair colour.
Katy Perry has teased fans by revealing she has changed her hair colour once again.
The 'Firework' singer has been sporting an electric blue hairdo in recent months but posted on Twitter asking fans to guess what colour she has gone for this time.
"Somehow in the middle of all this... I found time to change my hair colour... Finally... #takeaguess #foreverawalkingpantonepalette," Katy tweeted late last week (12th April).
The 'California Gurls' singer is well known for her outrageous hair styles and colours and has sported pink, purple, blonde, red, black and blue hair in the past.
Earlier this month Katy Perry unveiled the full trailer for her upcoming 3D concert movie Katy Perry: Part Of Me 3D.
