Cameron Diaz

continues to mourn the loss of her beloved father at home with her family, which meant skipping a press junket on Saturday, for her new movie with Ashton Kutcher, What Happens In Vegas.

But, Ashton showed up to the premiere with a hand-written note from his costar, thanking everyone for all of their love and good thoughts during this tough time. Here's what it said:

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
