The TOWIE beauty Instagrammed a close-up of her beautiful, vintage-style headband while filming for the new series yesterday (2 July).
Lauren joins a long list of celebrities who've been enjoying flamboyant headbands this summer.
A couple of weeks ago we spotted Laura Whitmore in a festival-fabulous band, and we've also seen Lauren's fellow TOWIE star Jessica Wright going all Bollywood on us with a gold chained headpiece.
Flowers have also been making a big appearance in the hair, with Kim Kardashian giving floral head garlands to her guests at her baby shower back in June.
The Only Way is Essex star, however, chose a more Hollywood movie star kind of look with this gorgeous Rock 'N Roll Vivien Rhinestone Headband, £42, rocknrose.co.uk.
The look was part of a whole 1920s theme that most of the TOWIE cast were partaking in...
"With the towie gang filmin, rockin the 1920's look #murdermystery #towie," Lauren posted, along with this pic (below) of herself with fellow cast members, Mario Falcone, Jasmin Walia, Diags, Abi Clarke and Frankie Essex.
Now, does that mean we can expect some kind of murder, mystery game in a future episode?
Ooh, the mind boggles!
