Jessie J Unveils New Dip-Dyed Red Hair
The 'Price Tag' singer has unveiled a new hair cut as she embarks on her UK tour.
Jessie J debuted her new dip-dyed locks with red tips as she visited the new state-of-the-art recording studio at the Birmingham Ormiston Academy.
But the London singer won't have the hair cut for much longer.
Speaking to Capital FM at the official opening, the star confirmed plans to shave her head next year to raise money for charity.
Jessie J also revealed that she accidently shaved off her eyebrows during a visit to Australia last year.
"I've cut my fringe before and cut my eyebrows off," she said. "I was in Australia and I cut my fringe too far out like I had a mullet, and I cut my eyebrows off by accident."
The singer also admitted that she dyes her eyebrows.
Jessie J kicked off her UK tour in Birmingham on Monday (17th October). You can see photos of Jessie performing live here.
