Leah, who is Elliott Wright's sister, showed off her new 'do during a recent catch-up with TOWIE star James 'Arg' Argent.
While out at dinner, the pair posed for a selfie together and it almost made us do a double take when Leah later shared it on Twitter.
Gone are her highlighted tresses and in their place she has a glossy, deep brunette mane thanks to some Great Lengths extensions. And we love it!
Leah has had her new look for several weeks now, although she has been keeping a low profile. But perhaps we will get to see her makeover in the new series of TOWIE!
Earlier today, a handful of TOWIE stars headed to the airport and jetted out to Tenerife to begin recording series 14 of the reality show.
Leah was on the plane, so we are looking forward to seeing how her brunette hair fairs in the sunshine and chlorine. We hope you've packed a good protective spray and conditioner, Leah!
