Cameron Diaz couldn't stop playing pranks on the set of her new movie.The actress plays Jules in What to Expect When You're Expecting, which follows several couples as they enter into parenthood.Matthew Morrison plays the father of Jules' baby Evan and had a great time working so closely with Cameron.
'She was exactly what you would expect Cameron Diaz to be like, just bubbly and funny and goofy and playing pranks. She was just wonderful, we had a great time,' he laughed.The movie is based on a self-help book of the same name. Matthew is pleased with the way the adaptation was handled as he thinks the movie really adds something to the tome.'It's a very popular self-help book,' he told a UK TV show. 'The book is a very scientific approach, this is what's going to happen to your body, this is what to expect. The movie humanises it, it brings interesting stories for birth and puts it into real life.'UK star Cheryl Cole appears in the film and Matthew was astounded by how natural she was. He was thrilled to meet her as he has become so familiar with her name.'Cheryl was great, it was great to meet her in person. I come to London a lot and you can't really escape London without hearing about Cheryl Cole in magazines and everything. It was great to meet her as a human being, she's just so lovely. She is great in it,' he said.
