Ex-NRL WAG turned boxer Arabella Del Busso stunned onlookers when she stormed the ring after a professional bout at the Misfits Boxing 22 event in Manchester, England over the weekend.

Dressed in daring white lingerie, the 35-year-old was caught on camera throwing kicks at her boxing rival Carla Jade following her fight against Daryn Harris, as security guards tried to restrain her.

'I’m the champ, fight somebody for f**kin' real! And that’s me! You’re next, b**ch. You’re next!' Del Busso screamed.

'We’ve seen how that turns out before, hun! All squealy, "I’m the champ!" You just came off a loss!' Jade shouted back, referring to the moment Del Busso was defeated by Andrea-Jane Bunker in their 2023 Misfits showdown.

The former SAS Australia star shared footage of what appeared to be a staged incident on Instagram on Monday. 

Del Busso explained in the caption that she halted proceedings at the boxing tournament to confront Jade.

'Little Bellsy storms the ring, challenging the current Misfits champion Carla Jade in Manchester, this morning,' she wrote.

Known for sharing steamy pictures on her social media, Del Busso also posted a photo of herself posing ring-side in lace underwear and a bra she paired with a sheer wrap.

Del Busso, whose real name is Donna Preusker, shocked fans when she launched a new career as a boxer.  

Making her ring debut in Melbourne in 2022, she later appeared on the undercard of the Misfits Boxing event in London the following year.

Del Busso was carried out to the ring for the match against boxer 'Lil Kymchii' on a golden chair before going on to beat her opponent via a unanimous decision at the Wembley Arena.

The high-profile event was headlined by British YouTube star KSI.

But Del Busso's bout was slammed by Aussie former world champion Ebanie Bridges, who claimed the bout wasn't real boxing, but more like the WWE.

Meanwhile, the ultra-fit athlete stripped down for a photo shoot on a balcony of a high-rise apartment in Melbourne in May.

She shared a video of herself posing using nothing more than three boxing championship belts to cover herself up.

The one-time reality star also wore a pair of black stilettos for the publicity stunt, pouting and moving from side to side as she flaunted the belts.

She included the cheeky caption, 'I know I'm your favourite'.

Del Busso made headlines last year when she was discharged from Australia's largest female prison.

The controversial sports star's release came after she served five months in prison for stealing $52,000 from her former employer, where she had worked as a receptionist for a Sydney medical business.

She has been embroiled in scandal since her relationship with former Bulldogs star Josh Reynolds came to an end when she faked three miscarriages with him.

After her release from Dillwynia Women's Correctional Centre in Sydney, she is understood to have begun a new life with her boyfriend in Melbourne.
