The 37-year-old Swedish model and the Italian fashion designer, who is thought to be worth over £400 million, had a child.
Roberto, who already has five children from his two prior marriages, stated the newest member of the family will be named Giorgio in honour of his father, who was murdered by Nazis during the Second World War.
“Sandra is doing fine”, he declared.
“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, just like my grandfather, my father, who was killed by the Nazis in the Cavriglia Massacre when I was four years old.
According to reports, the fashion designer purchased his partner a private island in Sweden in 2015. A spectacular £2.2 million Stora Rullingen isle off the coast of Strängnäs, some 50 miles east of Stockholm, is rumoured to have been givento Sandra by Roberto.
A four-bedroom home, hunting lodge, swimming pool, golf course, and the ruins of a Viking hill fort are all features of the 81.5-acre island.
Tommaso and Cristina, from Roberto’s first marriage to Silvanella Giannoni, whom he married in 1964 and divorced ten years later, are now joined by the couple’s new child.
Sandra won beauty pageants such as Swedish Miss Hawaiian Tropic and competed in Scandinavia’s Top Model. In January 2008, the celebrity was named Playmate of the Month by Playboy magazine.
Roberto has long talked about the difficult upbringing he experienced when his father was killed and left him speechless until he was 18 years old.
He earlier stated: “My father was shot by the Germans in July 1944, in a raid on Castelnuovo dei Sabbioni. He was a surveyor, he worked for a mine in the Valdarno… I didn’t speak until 18. But life has been kind to me [and I have been] rewarded… for everything.”
In 1975, the fashion mogul started the business that bears his name, which immediately gained notoriety for its animal print creations.
