'Adorable' Murphy protected by co-star

Hollywood beauty Brittany Murphy has been warned to tone down her friendly personality by her British co-stars in upcoming movie Love And Other Disasters.

The 8 Mile star is based in London all summer as she films the romantic comedy - and has found her warm southern manners are too 'nice' for the honest Brit cast and crew.

Co-star, comedienne Catherine Tate says: "She's genuinely, incredibly sincere but I think in this country we take that with a pinch of salt.

"She is genuinely adorable, but she will say to people who she doesn't know: 'Have an amazing day.'

"We say to her: 'Seriously, people will think you are taking the mickey out of them if you say that with that level of sincerity because we don't really do that over here!.'"
