Jessie J dyes her hair purple before showing off her derrière in monochrome print underwear

She made her return to the stage at the weekend after being forced to cancel concerts due to her ill health last week.
And Jessie J proved that she was well and truly back to her old self on Wednesday as she posed for a series of 'selfies' before taking to the stage at Edinburgh Castle, showing off her newly-dyed purple crop of hair.
The cheeky star posed in a pair of black and white print knickers and a matching vest top, getting someone to take a snap as she turned around to show her derrière.

Having clearly made a full recovery after her vocal issues, the 25-year-old seemed in great spirits as she growled for the camera.
And the Do It Like A Dude singer clearly wasn't shy about showing off her trim and toned body as she pulled up the T-shirt and thrust out her behind.
She clearly amused herself by doing it as the second snap that she posted was of her leaning back in laughter after her provocative pose.

Dye job: The singer seemed to have dyed her hair since last Sunday, sporting a bright purple crop as she posed up for a series of 'selfies'

The star was obviously keen to show off her new hair colour to her fans, having dyed her previously bright blonde locks a light purple.
Sticking to her usual style, Jessie wore a black baseball cap over her short crop of blonde hair and added a huge pair of gold hoop earrings.
But the singer obviously had second thoughts about her outfit, changing into leggings and a cropped top as she went on stage, in the same print as her previous outfit.
Later Jessie posted more snaps of herself as she headed onto stage: 'Smile smartie head,' she wrote, referring to her new hair colour.

And the star was back on top form as she took to the stage in front of the 10,000 crowd, belting out her best known tracks.
On Thursday Jessie posted a clip of her new track, which will feature in the new KickAss video.
'I wrote the soundtrack song for #kickass2 #themovie here it a little taste! #superheropose…,' she wrote.
Jessie has recently quit her role on BBC singing contest The Voice, followed by The Script's Danny O'Donoghue.
Speaking about leaving, she said: '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 was due to support Justin Timberlake at Dublin's Phoenix Park on Wednesday evening, followed by a performance in Paris on Thursday.
But the former The Voice judge was forced to pull out of both gigs as her vocal problems deteriorated.
Writing on her Twitter page at the time, she said: 'Heartbeats, I'm so sorry I can't be with you at my shows tonight in Dublin or tomorrow in Paris. I promise I will be back very soon!'
