Roberto Cavalli has become a dad for the sixth time at the age of 82.

The Italian fashion designer, believed to be worth over £400million, welcomed a baby with his Swedish model girlfriend Sandra Nilsson, 37.

Roberto, who already has five children from his two previous marriages, explained the newest addition to the family would be called Giorgio, in tribute to his father who was shot by Nazis during the Second World War.

“Sandra is doing fine," he said.

"The baby, who was born a week ago right here in Florence, is beautiful and it was really emotional to see him right after he was born.

“His name is Giorgio, like his grandfather, my father... whom the Nazis shot in the Cavriglia massacre when I was four years old, reports Novella 2000 magazine.

Roberto has been dating model Sandra since 2014.

In 2015, the fashion designer reportedly bought his partner a private island in her home country of Sweden.

Roberto is said to have gifted Sandra a stunning £2.2 million Stora Rullingen isle off the cost of Strängnäs, around 50 miles east of Stockholm.

The fashion designer is also a father to Robert, Rachele and Daniele from his second marriage to former Miss Europe model Eva Maria Duringe.

Roberto has dressed some of the showbiz world's biggest stars, including Kim Kardashian, who famously wore his floral print gown to the Met Gala when she was pregnant.

Supermodel Bella Hadid is also a big fan of the designer and regularly sports his stunning frocks on the red carpet.
