A MAJOR A-list celebrity put on a disguise and turned up at Pacific Park to mingle with an unsuspecting crowd at the fairground.
The star is known for her long blonde tresses and huge personality – so would you still have known that it was her?
Sydney Sweeney dressed down in a white graphic t-shirt and denim skirt for the day out with her friend Jayde.
She kept her identity on the down-low by covering her hair up with a brunette wig that only just fell to her shoulders.
The star finished the look off with a pair of chic sunglasses and a white set of nails.
Sydney shared a series of snaps from the day out to her Instagram page after, showing her and Jayde having fun on a ferris wheel and in the arcades.
Penned in the post’s caption, Sydney said: “when ur bestie shows up and says “here put this wig on””.
Fans loved the photos and how Sydney was able to have so much fun without being noticed.
One user said in the post’s comments section: “Great idea!!! This is what best friends are for.”
A second shared: “A couple of small town sisters on their big California vacation.”
A third added: “I didn’t even recognise her.”
The post comes shortly after Sydney has been slammed for posing naked in adverts for sports prediction platform, Novig.
In Syd’s latest Novig video, she posed topless with a pair of American footballs pressed to her chest and said: “There are grown men making spreadsheets to bet on what colour underwear I’m wearing. I mean, I’m flattered.”
The star also posed naked with balls, bats and racquets and said: “Think you know sport? Prove it.”
Critics are said to include models Kendall Jenner — half sister of Kim Kardashian — and Hailey Bieber, the daughter of actor Stephen Baldwin and married to superstar singer Justin.
