She's been dating a bodybuilder over the last few months.

And Brynne Edelsten certainly seems to be reaping the rewards from spending time with a gym bunny.

Millionaire Geoffrey's ex wife looked toned and trim as she was joined by her buff boyfriend Big Red Ra at the iHeart Launch in Melbourne on Tuesday.

Wearing a cropped green top the 31-year-old could have been ten years younger as she flaunted her taut stomach.

She teamed the daring top with a floor length black skirt with a huge slit up the side which served to show off her tanned legs.

The couple looked very loved up as they enjoyed a few drinks on the night out.

Red Ra went for an unusual look as he teamed a red and white plaid skirt with a denim waist coat with matching jeans.

Brynne spoke to OK magazine about her weight loss in May 2013, after losing 18 kilos.

At the time she blamed the stress of her marriage to Geoffrey.

The former fitness instructor, who later split with the businessman in January, said: ‘People think it happened in a much shorter period of time than it did – I’ve been losing weight for six months now.

‘There was a court case last year about a woman my husband may or may not have had an affair with – and that was a very stressful time for me. 

'When I’m stressed, I either overeat or don’t have an appetite – and I just didn’t have an appetite. After the first couple of kilos dropped off, I thought, ‘I’m going to make the most of this; I’m going to do it properly and eat healthily and start going to the gym.’

Brynne debuted her new slim line look on ABC talk show Reality Check earlier this month.

Proving she is looking hotter than ever she opted for a sultry two-piece ensemble that flaunted her toned body.

The couple first went public in June after sharing snaps of their mini-break to Australia's iconic Great Ocean Road and also posted a sweet photo collage of their vacation in Tasmania.

Since her split from her ex-husband, Brynne has been linked to nightclub owner Alex Roberts and club promoter Warwick 'Silverfox' Roberts, but this is the first man she's been seen spending any considerable time with.

Meanwhile, 71-year-old Geoffrey is dating 25-year-old American DJ and model Gabi Grecko, who is 46 years younger than her businessman beau.

With her bust being her signature asset, the blonde bombshell certainly had her cleavage very much on show in a plunging black blouse.

The fitted crop top with long sleeves may have concealed her slender arms, but was still skimpy enough to showcase her toned stomach. 

Opting for a pop of colour, Brynne sported a bright pink mullet-cut skirt which revealed her slim pins. 

And a pair of sparkly heels certainly added a bedazzled element to her onscreen look.

Welcomed onto the show by a round of applause from host Tom Ballard and panelists Ian 'Dicko' Dickson, The Block co-creator Julian Cress and media personality Marion Farrelly, bubbly Brynne was her flamboyant, smiling self on set.

Arriving on stage to present the cast with a copy of her bedazzled diary, the busty blonde held up the glimmering book but it was her sizzling body that captured the attention of host Ballard. 

'Brynne thank you so much for being here,' Tom addressed his celebrity guest.

'We know you love reality TV. What do you think you've learned from our show over the last couple of months,' he enquired, referring to the weekly panel discussion show injected with his usual comedy and wit. 

Proving she has the beauty and the brains, Brynne replied without any hesitation: 'You know what, I think Albert Einstein says it best when he wrote 'reality is all an illusion yet a very persistent one.''

Very impressed by Brynne's answer, Ballard said 'that was very insightful Brynne' before taking his appreciation for the stunner to the next level.

'I've got to say you look amazing today, you look really incredible,' he continued before holding out a red rose and asking her to accept his romantic gesture.

But it seems Brynne's heart only lies with her man Big Red Ra, with a stern 'no, no thanks' as her simple response to the television comedian.
