She lives an extravagant lifestyle, and it seems she'll soon be attending - and conducting - a wedding equally so.

Real Housewives Of Melbourne star Gamble Breaux, 43, is set to oversee an interesting ceremony between a dog and a cat at the weekend in an extravagant affair estimated to cost $20,000.

The two furry friends - a white feline called Bentley and Pomeranian Charlie - are tying the knot in Sydney, with each arriving at the event in separate Bentleys.

Wedding celebrant? The Real Housewives of Melbourne star Gamble Breaux, 43, is set to oversee an interesting ceremony between a dog and a cat, in Sydney at the weekend

Ready to go: The two furry friends tying the knot in a lavish and estimated 20k affair, are a white feline called Bentley and Christa Billich's (R) pomeranian, Charlie, who will show up to the event in separate Bentleys

According to the invite, the big day will be held at waterside inner-city venue Cadmans Cottage, followed by a reception at Billich Gallery.

The dog taking part belongs to Gamble's close gal pal Christa Billich, the wife of artist Charles, 80, who has guest starred on the reality TV series.

Kids are welcome, and guests can tuck into caviar and sip on French champagne.

For a cause: Also sent around with the invite was a painting of the pets, saying they support gay marriage

Also sent around with the invite was a painting of the pets stating that they support gay marriage.

'Love has no bounds,' it reads, 'Gay marriage is an expression of liberty and we extend the freedom at the Billich Gallery for any expression of love and the celebration of unions.'

'We support the dynamic of our civilisation and our sociological progression.'

Former art consultant Gamble indeed seems like the animal lover, with two Pomeranians, Cash and Wicket and a 'puppy retreat' in her Melbourne mansion.

Last month, the star, who is married to eye surgeon Dr Rick Wolfe, wrapped up filming for the next season of The Real Housewives of Melbourne.

Gamble told Daily Mail Australia the next season is set to be juicy, with one piece of gossip so 'damaging' it may not get to air.

'There's some salacious gossip this season,' she said, 'I was shocked - it's jaw-dropping.'

'We'll see if it makes it in because it might be too damaging.'

Gamble, who joined the show in its second season alongside Pettifleur Berenger, admits that she's feeling much more comfortable now that she's got some experience under her belt.

'I've settled in much better because this is my second season. Last season was really difficult,' she confessed.

She continued: 'The relationships are really deep now. We have real friendships and real grudges.'

Adding some fireworks to the third season will be Susie McLean - a Toorak socialite and ex-wife of former St Kilda Football Club president Rod Butterss.
