Britney Spears changed up her hairstyle last week and is now rocking pink and blue extensions. The 30-year-old singer showed off her new 'do on stage at the iHeartRadio Music Festival in Las Vegas on Sept. 21.
Lovato, 20, who previously styled blue and pink hair streaks on separate occasions over the summer during X-Factor's nationwide talent auditions.
"I love changing my hair a lot -- I think it's fun," Lovato told Allure.com in an August 2012 interview. "I used to always want to dye my hair blue and purple and pink when I was younger. But I was busy trying to make it in the industry as an actress, and it was hard to go in for auditions with blue hair. And so when I heard of the dip-dye trend, I loved it, and I felt like I could finally dye my hair blue. You know you've made it when you can dye your hair blue."
But the "Skyscraper" singer has changed up her style once again. Lovato tweeted a photo of her very blonde hair and wrote, "Guess what's back, back, back, back again . . . Bangs are back, back, back tell your friends."
