Sophie Monk is unrecognisable in her latest social media post.

The media personality, who recently hosted the TikTok Awards in Sydney on Wednesday, took to Instagram on Thursday to show off a fresh new look.

The blonde bombshell revealed that she had gone dark, showing off cascading brunette locks that reached her waist.

‘Not going to lie. I do feel smarter being brunette @kokomayneluxehaircollection thank you sooo much,’ she captioned the post as she flaunted her natural-looking wig.

In the video, the 45-year-old struck dramatic poses in front of a wind machine, wearing a sheer brown corseted dress and a sparkly low-cut frock.

The Love Island host opted for a dramatic eye and lined lips as she showed off her new hair to her fans.

Sophie made a show-stopping entrance at the TikTok Awards on Wednesday night – and left many fans doing a double take.

She and Aussie drag queen Courtney Act appeared to be twinning, both choosing striking black ensembles that featured thigh-high splits, with their blonde locks styled to perfection.

Sophie stunned in a sleek designer gown that hugged her figure, her straight hair framing her radiant smile as she posed for photographers.

Meanwhile, Courtney mirrored the look with a chic bandeau top and flowing skirt.

Her long blonde hair was parted in the middle, giving the impression that the duo could have been mistaken for sisters.

The similarities didn’t stop at their outfits.

Both stars carried themselves with equal glamour and confidence.

The twinning look was the talk of the night and had fans debating over who wore it better.

Adam Hyde, MAFS star Jules Robinson and social media sensation Indy Clinton also rocked head-turning looks on the red carpet.

They were joined by Today’s Karl Stefanovic and Sarah Abo, and media veteran Jessica Rowe.

Fifteen awards were handed out on the night.

The event celebrates the country’s top creators across comedy, fashion, sport, business and music.
