The stunning Beatrice, who is often spotted accompanying Pierre to high-profile events, has recently spoken about wanting to start a family.
"I'd love if Pierre became the father of my children," Beatrice, 29, told Vanity Fair Italy. "He would be so good and I think together we could create a very stable family. But we haven't reached that point yet."
"At the moment we are both happy," she added. "[But one day] I would like the responsibility of a family."
