The Essex lass stopped by Malcolm Murphy Hair salon earlier today (20 August) ready for her barnet makeover, and emerged looking very glam with her new lighter locks...
Lydia was previously rocking sleek caramel brown tresses, but now she's lightened up for summer by adding a mix of golden and honey shades to her lengthy mane.
Posting an Instagram snap while sporting her fresh dye job, Lydia wrote: "That's right I'm a blondie again! Thank you as always to my hair guru @malcmurphy @malcolmmurphyhair #NewHair #Blondie."
And it's not just her latest hair colour we're loving - Lydia's bonce looked super-luxe and glossy too, styled in a middle parting with the lengths tonged into bouncy, voluminous curls.
The starlet made her TOWIE comeback earlier this year in season 12, where viewers saw Lydia grow close to her ex-boyfriend James 'Arg' Argent.
She'll start filming for the new series soon too - it's thought to be hitting our screens in October kicking off with an Ibiza special. What better excuse for a new 'do?!
