Christine Anu shows off her edgy new look as the 1990s pop star reemerges for performance on Triple J

Christine Anu was one of Australia's most beloved pop stars in the 1990s. 

And the singer, best known for her chart-topping pop hits Island Home and Party, has reemerged for a new performance looking very different to her heyday. 

The 56-year-old was youthful and edgy in a graphic rock shirt and with her locks dyed pale blue as she made an appearance on Triple J radio's Like A Version.

The show, which sees famous singers cover the songs of their favourite artists, invited Christine along to tackle a track from a fellow Aussie last week. 

Christine covered singer-songwriter Boy Soda, with her own version of his song, Lil' Obsession. 

The performer said that she had long been awaiting an invite to the music show. 

'I've been waiting my whole life to do Like a Version. Thank you, and you're welcome,' she said in an interview on the show. 

Christine also explained her choice to cover a hip hop track.  

'I've always had an obsession with R&B, soul music and hip-hop. I've watched, over my 30-odd year career, those genres grow quite tremendously,' she said. 

The Australian singer has kept a lower profile lately, but returned to the red carpet at the APRA Awards in Sydney in April. 

In recent years, Christine has opened up about shedding an incredible 46 kilograms. 

'(It was) emotional eating. You have to say nice things to yourself,' Christine revealed on Today Extra. 

Christine explained that she dropped weight from her heaviest weight of 106 kilograms.

Alongside gentle exercise including walking and overhauling her diet, the mother-of-two went on to explain the importance of self-love.

'(I was saying to myself) 'I deserve to be healthy, I deserve to be myself, I deserve to be loved'.' 

Christine previously told Woman's Day: 'I've tried every diet under the sun but I've never tried the diet of self-love - and it really does come down to the relationship you have with yourself.' 

The star, having been nominated for 17 ARIA Awards, weighed over 100 kilograms following her divorce from childhood sweetheart Simon Deutrom.

'I was clearly very unhappy in my marriage and I just lost all self-control,' she said. 

'I was eating drive-through takeaways in the middle of the night and eating at irregular times.'

Christine and Simon first met at school, and they finally wed in 2010 in a clifftop ceremony on Christine's native Torres Strait Islands.

But they confirmed their split in 2016 after six years of marriage. 

In order to get down to 60 kilograms, Christine began dieting, meditating, dancing, walking and doing yoga.
