Cameron Diaz and Gwyneth Paltrow gatecrashed a wedding show.

The two actresses were staying at the Sir Christopher Wren Hotel in Windsor, Southern England, over the weekend and when they found out The Windsor Wedding Show was being held there on Sunday (16.09.12) they couldn't resist having a look.

Single Cameron and Gwyneth - who is married to Coldplay singer Chris Martin - had a look at all the displays and spent time staring at the bridal gowns.

A source told the Daily Mirror newspaper: ''The girls were chatting away and they wandered in. They perused the cakes, photography exhibitions and bridal wear. They were giggling and aahing at all the displays.''

After seeing the show, the pair - who became close friends after the death of Gwyneth's TV producer father Bruce Paltrow in October 2002 - then spent the rest of the afternoon together and were even spotted on a hired boat on the Thames.

Cameron has previously insisted she isn't too bothered about ever tying the knot, saying: ''I'm not sitting there going, 'Oh my god, when am I going to get married?'''

The 'Bad Teacher' star is currently in the UK to film Ridley Scott's thriller 'The Counselor' with Brad Pitt, Michael Fassbender and Penelope Cruz, while 39-year-old Gwyneth lives in London with her husband Chris and their two children, Apple, eight, and son Moses, six.

Cameron has dated a string of famous men over the years, including New York Yankees baseball star Alex Rodriguez, Justin Timberlake and Jared Leto.

She was recently spotted cosying up to newly single Tom Cruise after the 50-year-old actor was spotted at Cameron's 40th birthday party earlier this month.
