The former The Only Way Is Essex girl spent hours having her blonde makeover and while we've not seen her new do on the red carpet yet, she treated us to all manner of before and after snaps on Instagram...
Maria has been sporting dark hair for a few years now, switching up her infamous red locks with a fringe and new, chocolatey-brown colour last December.
And the last time we can remember her sporting fair hair was way back in 2012 when she enjoyed a few months during the spring as a bubbly blonde.
We do love a celebrity who's brave enough to totally change her look and Maria is a great example of being experimental with her hair colour while sticking with shades that suit her complexion.
A lesson to all colour-happy celebrities out there...
For her latest look, Maria visited Lil K's Hair salon in Derby where she had Easilocks extensions fitted to create her new warm blonde do.
Easilocks are much kinder to your natural hair than a lot of extensions brands as they're neither glued, plaited nor heat sealed meaning they cause much less stress on your scalp.
That'll be why they're a big favourite in TOWIE land, with the likes of Amy Childs, Chloe Sims and Lucy Mecklenburgh all being huge fans.
We're loving the look of Maria's new do which appears to be much more natural than her last stint as a blonde.
The colour seems darker at the roots and the extensions have been graduated perfectly to give an overall blonde, ombre look.
Can't wait to see it in all its glory, Maria – roll on (or indeed, roll out!) that red carpet...
