Great British Bake Off judge Paul Hollywood has revealed his legal trials at trying to patent his surname.
The star of the popular BBC One show revealed he faced a backlash from "a huge amount of people in California" over calling himself Hollywood.
Appearing on The Graham Norton Show, he said: "The lawyer in London sent out this letter saying what I wanted to do and a huge amount of people from California said that I couldn't call myself Hollywood, so my lawyer sent back letters saying 'Paul's family name goes back 600 years and if you can prove Hollywood has been around before that he will back down, otherwise he will sue you for using his name on a sign on the side of a mountain!'
"They dropped everything!"
The winner of the last series of the baking show, Nadiya Hussain, baked the Queen's 90th birthday cake.
"She texted me when she was asked to do it, saying, 'You'll not believe what's happened.' She was scared obviously but good on her," Paul commented.
Dame Joan Collins also appeared on the show as a guest and spoke of her sister Jackie's braveness at keeping her illness a secret.
"She was very brave to do that. I think if you are a celebrity in Hollywood and there is even the slightest hint that there is something wrong, you will be hounded by the press," she said. "Jackie didn't want that and she wanted to keep herself completely private. She was a very private person despite what she wrote."
Dame Joan's younger sister, a respected novelist in her own right, died of breast cancer last year, just two weeks shy of her 78th birthday.
A posthumous work could be in the pipeline as Dame Joan revealed her nieces had found books written by Jackie when she was young.
"They are good - all about teenagers in the 50s - they are really interesting and I think we might publish."
The author and actress also spoke about being made a Dame in the New Year's Honours list, describing it as the "greatest day of my life".
She said: "Really extraordinary because to receive it is a great honour and Prince Charles pinned it on me and said, very nicely I thought, 'It's about time too!'"
Downton Abbey actress Lily James and Game Of Thrones star Richard Madden completed the guest line-up to talk about their latest venture - starring as Romeo and Juliet in Kenneth Branagh's new production of the famous play.
The Graham Norton Show airs on BBC One at 10.35pm.
