Following in the footsteps of Kylie Jenner, the singer unveiled her eye-catching new look to her 230,000 Twitter followers on Wednesday morning (15 April).
Certainly different, right?!
Tamera's fans seemed to love it, posting lots of complimentary messages about her 'do on Twitter and Instagram.
Her dramatic makeover comes the week after Kylie Jenner also switched her dark hair for a bright blue colour. In her case, it was a new look for the weekend's Coachella Festival.
And Tamera and Kylie aren't alone!
Hilary Duff had us all talking when she dyed her hair green earlier this year, while Kim Kardashian West and Chloe Sims have both gone mega blonde in recent weeks. And let's not forget favourites like Katy Perry and Rihanna, who change their hair colour as often as their socks!
Tamera is currently working on her debut album.
Following her time on X Factor, she signed a deal with Simon Cowell's Syco Records, saying: "So guys, I have news. I'm the newest member of Syco music!! Get that work! I'm so blessed to have my dream job at the age of 17. Thank God always."
