The 'Spring Breakers' star debuted blonde locks at the Coachella Valley Music and Arts Festival last weekend, reported Us magazine.
"Mermaid hair! A big thank you to my stylists. Can't believe Riawna Capri made me this blonde!," she wrote on Instagram.
The 'High School Musical' actress, 25, also expressed her appreciation for her lighter locks beside a pic of herself, clad in a bikini top and shorts, grinning underneath a Bob Marley-style sun design plastered against a wall.
