The youngest child of late billionaire Richard Pratt has tied the knot in a lavish wedding in Sydney.

Pratt, 24, and finance analyst partner Nassib Thoumi appear to have spared no expense for the nuptials, which were attended by a number of familiar faces.

Attending to Pratt in the wedding party were Dakota Phillips Glyde, for whom she herself was a bridesmaid last year, and Tiffany Bowen-Hughes, the daughter of Dotti retail co-founder Linda Bowen.

“It was an absolutely beautiful wedding,” said one guest. “Paula looked incredible, stunning. It was a very family wedding, which was so nice.”

Born in 1997, Pratt, the product of the Melbourne billionaire’s 18-year-long relationship with Hitchcock, reportedly won a settlement from her late father’s estate worth millions.

The cardboard king died in 2009 and was ranked the fourth richest person in Australia with a worth of $5.48 billion.

He had three adult children to wife Jeanne Pratt – Anthony Pratt, Heloise Waislitz and Fiona Geminder.

Paula grew up in Sydney’s east and studied finance at Sydney University. She and Nassib are understood to have met while studying.
