The High School Musical star opted for a fab new 'do as she joined the fash pack at Coachella festival in California this weekend (12 April).
Taking to Instagram to flaunt her new lighter (and much, much longer!) bonce, the starlet wrote: "Mermaid hair!!!! A big thank you to @ninezeroone and @greatlengthsusa #blondesdohavemorefun =) can't believe @riawnacapri made me this blonde!!!"
It's certainly a big change for Vanessa as she's famous for her deep brunette locks, although she did flirt with a blonde mane while filming her flick Spring Breakers.
She's also a huge fan of the ombre look - Vanessa showcased a gorgeous caramel dip-dye back in August 2013 before switching things up with an autumnal burgundy red hue later that year.
Clearly enjoying herself at the music festival, Vanessa posted another snap while lapping up the sun and striking a pose alongside a pal and her little sister Stella.
Other A-listers at the festival included Kendall and Kylie Jenner, Selena Gomez, Emma Roberts and Kate Bosworth, along with Cara Delevingne and Sienna Miller, to name just a few.
Talk about a star-studded event!
