New details about Crown Prince Frederik’s friendship with socialite Genoveva Casanova

New claims have surfaced about Crown Prince Frederik’s friendship with a Mexican socialite as he and Princess Mary put on a brave public face.

New claims have surfaced regarding Crown Prince Frederik of Denmark’s friendship with a Mexican socialite following rumours of an alleged affair.

The future King has been dogged by allegations of infidelity in recent days after Spanish magazine Lecturas printed photos of Frederik, 55, and Genoveva Casanova, 47, on a night out together in Madrid in October.

Ms Casanova has flatly denied any suggestion of an affair and has indicated she may take legal action.

In a new development, Spanish TV presenter Susanna Griso revealed on her current affairs show on Friday that a member of “Geneveva’s entourage” had shed light on their friendship, which reportedly began after they met in the Alps on a high-end hunting trip.

“They know each other and have friends in common. They usually meet several times a year,” the TV host said on her show, as per Lecturas magazine.

“They tell me that they are private meetings that are with more friends of the group, some members of royalty. They meet and sleep in private houses.”

As speculation swirled around the pair this week, Lecturas printed further details of Frederik and Ms Casanova’s meeting, claiming they took in a Picasso exhibition before walking around a park and dining at a local restaurant.

The magazine then alleged that Frederik and Ms Casanova both went to her apartment building separately, and re-emerged two hours later.

Frederik met then-Mary Donaldson in Sydney during the 2000 Olympics and the couple tied the knot in a lavish, fairytale royal wedding in Denmark in 2004.

They share four children: Prince Christian, 18, Princess Isabella, 16, and 12-year-old twins Prince Vincent and Princess Josephine.

Princess Mary appeared to be taking the added scrutiny in her stride in the wake of the rumours, as she joined Frederik in hosting the King and Queen of Spain on a state visit to Copenhagen.

Meanwhile, according to Ms Grislo, Ms Casanova is now reportedly in hiding after boarding a plane for an unknown destination and switching off her phone.

“The two have been in contact and have decided not to speak and not to fuel speculation at all,” the TV host claimed.

The royal couple has not commented publicly on the articles but Ms Casanova has “flatly denied” all accusations regarding an alleged affair.

“I flatly deny the statements that suggest a romantic relationship between Prince Frederick and me,” she told Hola.

“Any statement of this type is not only completely untrue but also distorts the facts in a malicious manner.”
