Melbourne 'It girl' Georgia Geminder and investment director Matthew Danos are expecting their first child. 

Georgia, 28, shared the good news in a social media post this weekend, showing off her baby bump in a sweet selfie. 

'We are over the moon,' the heiress wrote alongside the image, which showed her cradling her belly in a blush pink dress. 

The baby news comes just three months after the couple tied the knot in an opulent society wedding in December. 

The event took place in the ritzy suburb of Kew, and was a traditional Jewish ceremony followed by a black tie reception inside a marquee at Raheen, the Pratt family mansion. 

Georgia, who is the model granddaughter of Australia's late 'Cardboard King' Richard Pratt and eldest daughter of billionaire packaging magnates Raphael and Fiona Geminder, looked like modern day princess in a beaded strapless fishtail gown with matching gloves and a tiara.

She accessorised her look with a diamond and sapphire choker necklace, drop earrings and a dramatic ivory veil. 

Proving that less is more, the heiress opted for an understated makeup look consisting of foundation and mascara.  

The glamorous toothpaste company owner wore two dresses on her big day, changing into a feather-covered mini dress for the reception. 

For accessories, the blushing bride wore an elegant diamond tennis bracelet and chunky nude heels. 

Matthew meanwhile looked sharp during his trip down the aisle, wearing a white blazer, black suit pants and black bow tie.  

Georgia and Matthew married under a large outdoor chuppah (a Jewish wedding canopy) surrounded by friends and family. 

The aisle was made from a reflective surface that imitated water and surrounded by bunches of white roses. 

A leaked wedding invitation reveals the couple asked guests to make a donation to a specified charity, rather than bringing gifts. 

Georgia's mother Fiona owns cardboard giant Visy and is worth a reported $3.4billion, while her father Raphael - who is also on Forbes Rich List - has a 40 percent share in plastics manufacturer, Pact.

Her grandfather Richard Pratt, an immigrant born in Poland whose family fled to Australia months before the German invasion, was a leading figure in Melbourne society until his death on April 29, 2009.

Ms Geminder, a former Australian Grand Prix ambassador, spent seven years modelling in Australia, London and Los Angeles before quitting the industry to create a non-toxic toothpaste brand in 2020.

In 2020 she launched Gem, a clean beauty company specialising in oral care that replaces chemicals with natural ingredients.

Her new husband Matthew is the managing director of James Richardson Investments, part of a furniture, hospitality, real estate and retail corporation headquartered in Melbourne's north.

The company is best known for its duty-free outlets in airports and border crossings across Australia and the Middle East. 

James Richardson is a household name in Israel thanks to its multiple stores in Ben Gurion airport, Israel.
