Still mourning the death of her father, Cameron Diaz skipped a press junket for What Happens in Vegas in L.A. on Saturday.

Co-star Ashton Kutcher delivered the following hand-written note from Diaz, whose father Emilio died at the age of 58 from post-influenza MRSA pneumonia on April 15.

Diaz wrote:

"First of all I want to thank all of you for your support over the years.

"So many films, so many weekends discussing films. I was really looking forward to this weekend getting to talk to my friends about a film that I am so proud of.

"Due to the loss of my father I have chosen to be with my family this weekend. But it was important for me to convey to all of you how much I love this film. We really did have the best time, most fun and laughs making it. I know that the stories Ashton, Rob [Corddry] and [Director] Tom [Vaughan] share with you will illustrate that point. I was fortunate to work with a group of truly gifted individuals that share the common denominator of a generous heart and wickedly sick sense of humor.

"This weekend I am screening What Happens in Vegas for my family. It was a unanimous decision that we all needed to share a good laugh. After all that's why we make films like these. So people can leave behind their worries for a couple of hours. Have a good laugh.

"I picture all of your smiles and it makes me happy.

"Thank you for your continued support. It is much appreciated.

"Cameron."

In What Happens in Vegas, which opens May 9, Diaz and Kutcher play newlyweds who fight over slot machine winnings.

Kutcher joked to reporters at the junket that working with Diaz was "horrible."

"I mean, showing up to work having to look at a good looking woman who is funny and happy to be alive and joyous and nice to people was a nightmare," he said.

"I don't think that there is anybody like her she is maybe the only true comedic leading lady in our business right now she has really owned that craft," Kutcher added.

Production on the Diaz' latest film, My Sister's Keeper, was halted on news of her father's death. The actress is expected back to work this week.
