Talk show host, Jonathan Ross, has been spotted in a Lancashire city filming a mystery TV show.

Heather Charnley and other locals recently spotted the celeb with filming crews outside Lancaster Castle.

He also visited Lancaster office space and community hub The Storey, as well as Williamson Park. 

In Heather’s picture Jonathan, affectionately known as ‘Wossy’, can be seen outside the castle dressed in a pink suit jacket and brogue shoes.

He was seen with four members of a TV production company.

The photo is captioned: “Look who we’ve just spotted at Lancaster Castle".

Hundreds of people have since interacted with, liked and shared the post; many were curious about what they were filming.

One person said: “I wonder what they are filming?”

“He is so nice,” said Paula Harrison.

Another said: "I just walked past him and noticed the jacket and shoes, totally didn’t recognise him."

Another didn't approve of his outfit choice and said: "He needs locking up wearing clothes like that."

“I love Jonathan Ross his interviews and show is brilliant. Thought someone might know what he is filming,” said another.

Not much is known about the TV show The Jonathan Ross Show host is currently filming.

Lancaster Castle has also remained tight-lipped about specific details but say they believe he is filming a show about myths, legends and folklore.

If so, perhaps he is exploring the apparent ‘haunted history' of the castle or the folklore surrounding the Pendle Witches, who were taken to court here.

Jonathan has been spotted with production crews, wearing the same suit, across other parts of the UK.

Last week he was seen in the Yorkshire seaside town of Whitby - famed for its links to Dracula - where he was seen outside a fish and chip shop and on the Whitby Abbey steps.

Punters also saw him Ross enjoying a drink at a local pub.
