Although one is married and the other says she's doesn't dream of a white wedding, Gwyneth Paltrow and Cameron Diaz couldn't resist taking a sneak peek when they stumbled across a bridal fair.
Finding that The Windsor Wedding Show was being held in their hotel, the friends decided to experience some romance.
Onlookers said the Hollywood stars were "giggling and aahing" at the displays as they examined wedding dresses, tried out cakes, and visited photography exhibitions.
Having recently spoken of her proud singledom, Cameron, 40, is not someone you imagine succumbing to the charms of a wedding fair.
She said: "I'm not sitting there going, 'Oh my God, when am I going to get married?'"
However, her friend Gwyneth, 39, has been happily married to Coldplay front man Chris Martin for nine years.
The Avengers actress cites her husband's British sense of humour as just one of their ingredients for a happy marriage, with the singer apparently known as a master of puns.
She said to In Style magazine: "We laugh a lot, and at the same jokes. We like music, and we like to do the same things."
