Big Brother star Hannah Campbell doesn’t look like this anymore as she shocks her co-stars with glamorous blonde transformation

She rose to fame as the fun-loving brunette on Seven’s rebooted season of Big Brother Australia this year.

Now almost five months on from making her national television debut, Hannah Campbell has undergone a glamorous blonde transformation.

The 26-year-old Perth-based reality star almost looked unrecognisable as she debuted her dramatic new look to Instagram on Friday.

The communications specialist has decided to swap her brunette tresses for a much lighter look.

‘I just wanted a new look after Big Brother,’ she told Daily Mail Australia of her transformation on Sunday.

And her transformation certainly didn’t go unnoticed with her former housemates.

Marissa Rancan praised her new look writing, ‘Yassssss!!’ along with a series of hearts. While Talia Rycroft wrote: ‘HOLY S**T BALLS.’

Xavier Molyneux joked that Hannah was certainly out of Kieran Davidson’s league, as the pair were known to flirt on-and-off the series.

Hannah appears to be making the most of her newfound fame as a social media influencer since leaving the Channel Seven reality show.

She has since documented her visit to cosmetic clinics, various red carpet events and teeth whitening solutions. 

Back in August, Hannah revealed she chose to go on to the competitive reality show instead of her best friend’s wedding.

She dished about making the difficult decision in a post on Instagram and admitted that ultimately she knew she couldn’t say no to the exciting television opportunity. 

‘I had to decide between going on Big Brother or attending one of my best friend’s wedding. For me personally, I knew I had to take the @bigbrotherau opportunity.

Hannah explained as soon as she was evicted she called her best friend and made it into her wedding video.
