Warner Bros has stopped a London single mother from hosting a Harry Potter-themed Hallowe’en dinner at her house.

The Hollywood studio sent the woman, who runs a supper club from her home, a terse letter warning her on copyright infringment of the Potter series, written by JK Rowling.

The woman advertised Harry Potter Night dinners on her blog, selling tickets for £25 each. Her Potter-inspired menu included butterbeer, dandelion wine, pumpkin soup, mint humbugs and cauldron cakes.

The studio informed the woman that it was delighted she was a fan of Harry Potter but that “no one may copy, license, exhibit, reproduce or otherwise trade on the Harry Potter Properties without the prior authorisation and consent of Warner”.

The woman changed the name of her already sold-out dinners on Friday and Saturday nights to Generic Wizard Night.

New Moon actress Kristen Stewart has said she doesn’t want to be a celebrity she just wants to act.

Kristen, 19, hit the big time after appearing in Twilight and will reprise her role for the movie’s sequel New Moon, which is out in cinemas later this month.

She said to Britain’s Fabulous magazine: “I don’t want to be a movie star like Angelina Jolie. Nothing about being a celebrity is desirable. I’m an actor. It’s bizarre to me that everybody’s so obsessive.”

Kristen also said isn’t fussed on shopping and likes to buy her shoes on the auction site eBay.

She said: Fashion is not something I think about. I’m not a big shopper. My style is T-shirts. My favourite ones are my brother’s old worn-out ones. I get my shoes on eBay.”

The singer turned actress apparently had a bit too many martinis one of these nights because she went online and tweeted a neat message for her father. This is what Lindsay Lohan wrote: “My father is a lunatic&doesn’t even deserve such a title since he’s never been around in my life other than when he’d threaten me&my family. He should be where he has always put himself after verbally abusing and physically abusing people all my life-behind bars. Its so sad to get a phone call from my baby sister just now asking, “why is daddy doing this?” Through tears. He’s crossed the lines&hurt me&my family 4 the the last time…. So much for having a ‘dad’….. I’m going to spend some time with the ones that love me&i love now. I appreciate those who continue to support me. My fans keep me strong&i love you all so much for it! My second family is what you are to me.” Big words for somebody like Lindsay Lohan… but then again, her synapses might be working overtime because of the alcohol.
