Family day out: Jonathan Ross poses with (left to right) daughters Honey and Betty, wife Jane Goldman and son Harvey at the Wizarding World of Harry Potter

He's long been a fan of J.K. Rowling's Harry Potter book series, and the subsequent film franchise.

So it's no wonder Jonathan Ross looked as though he was in seventh heaven today as he visited the Wizarding World of Harry Potter theme park in Universal Studios, Orlando, Florida.

Accompanied by wife Jane Goldman, daughters Betty and Honey and son Harvey, Ross even wore the scarf donned by Gryffindor students of the Hogwarts School of Witchcraft and Wizardry as he posed for photographers at the park.

Youngest daughter Honey also got into the spirit of things with a Gryffindor scarf, which retails for $34.95 in the official theme park store.

But Betty and Harvey declined to don the accessories, along with Jane, who perhaps thought the maroon scarf might clash with her bright red hair.

Ross has been a fervent fan of Harry Potter since Rowling wrote the first novel in 1997.

Since then, he has interviewed both Rowling and various stars from the film adaptations, including the main characters played by Daniel Radcliffe, Emma Watson and Rupert Grint, as well as other Potter actors including Robbie Coltrane and Jason Isaacs.

Wizarding world: The theme park at Universal Studios has proved a huge success

Ross is currently enjoying a break with his family before he returns to our television screens next month in ITV magic show Penn and Teller: Fool Us, which premieres on ITV1on January 7th.

It is also claimed he is hoping to launch the show in America, and is set to fly to Los Angeles to film a pilot episode for the US version of the programme next month.

A source told The Sun: 'September Films are taking Jonathan to the US to pilot his ITV show and they think he can be a star over there.

'They have big plans for him, and they think his type of presenting will go down really well. Magic is also being seen as the next big thing.'
