Big Brother winner Nadia Almada unrecognisable 20 years after winning the show

BIG Brother winner Nadia Almada has completely changed her look nearly two decades after winning the juggernaut show.

The now 46-year-old made history as the first transgender housemate on the Channel 4 show.

Back then she wowed fans and her housemates with her big curls and even bigger personality.

Nowadays she looks very different, and was earlier she stepped out wearing an oversized shirt dress and black wedges.

Nadia teamed the look with pink nails and wore sunglasses perched on top of her bleached hair.

The Portuguese reality star was Big Brother's first ever transgender contestant when she walked into the house in 2004.

Nadia was loud and proud, wearing her heart on her sleeve, and often paraded around the house with big black hair and in glam outfits.

She quickly became very popular with viewers thanks to her fiery temper and hilarious humour.

Back in her Big Brother glory days Nadia's Diary Room appearances proved very emotional.

She was worried the UK public would judge her for keeping her transgender identity a secret.

Of course, that only made her triumphant exit even more emotional - especially as she scooped 74 per cent of the vote.

When host Davina McCall announced she was the winner, beating Jason Cowan and Daniel Bryan, she screamed with joy.

That series was the one with the infamous Fight Night.

The furious display happened after contestants Emma Greenwood and Michelle Bass, who housemates thought had been booted out, returned and let everyone know they'd seen all that had been said about them.

One thing led to another - especially given there was booze involved - and things became so heated security had to calm things down.

After her win, Nadia released a single called A Little Bit of Action.

And in 2010 Nadia had another stay in the famous house as part of Ultimate Big Brother, where she was pitted against other previous contestants including Makosi Musambasi and Josie Gibson.

The late rapper Coolio was also there, with Nadia and Gangster's Paradise star having several blazing rows.

These days it seems Nadia is much calmer, living life as a hair stylist in London.
