All The Colours Of The Rainbow? Singer Dyes Hair Blue!

Turns out Rihanna isn’t the only pop star who has opted for a slightly unusual hair colour this week.

Jessie J unveiled her new blue do on Twitter yesterday although it doesn’t look like it’s set to last as the singer captioned the picture: “Blue hair, don’t care... Just for today? Lol”.

The singer, who shaved her head for Comic Relief earlier this year, dyed it purple (or as she called it “Powple”) before she went blue.

Jessie has also been busy promoting her new track for the Kick Ass 2 soundtrack and talking about her departure from The Voice.

She told reporters: “I’ve absolutely loved my time on The Voice. I shall be keeping a very close eye on series three, showing my support in every way I can.”

Jessie dyed it purple first.
