LISTEN: Why Princess Beatrice Can’t Have a Big Wedding Like Her Sister
However, Mollard believes it might be pure speculation and that the rule may not be enforced.
"We know Meghan married in the Church, she was a divorcee. I can’t see any reason why Edoardo is not a suitable partner to be married in a similar manner to Eugenie."
"He has a son he clearly adores, the relationship didn’t work out with the child’s mum, but you really just want people to be happy in the end, don’t you?"
"I would hope there wouldn’t be any censure on him because of the fact that he has a son."
Princess Beatrice has been dating the 34-year-old since October last year, making their first public appearance at the National Portrait Gallery gala, along with Princess Kate and David and Victoria Beckham.
The two have been friends for years, with Beatrice attending the funeral of Edoardo's stepfather, Christopher Shale in 2011.
The couple is as official as can be, with Edoardo accompanying the royal to her sister Eugenie's wedding last October, as well as Lady Gabriella Windsor and Thomas Kingston's wedding in May.
