ameron Diaz’s ex-boyfriends Justin Timberlake and John Mayer offered their love and support to the actress at a memorial for her late father Emilio Diaz. Timberlake and Mayer attended the service Sunday and stayed until after most of the guests have left.

Emilio, 58, died of pneumonia suddenly last Tuesday morning. A witness said that the memorial, held in Seal Beach, was a non-traditional service with most guests wearing Hawaiian attire. “Most people started arriving at 1:30 and hardly no one wore black. Lots of people were wearing Hawaiian shirts. It looked more like a party,” says the source.

The 35-year-old actress and her family are requesting that donations be made to Surfrider.org or Reefcheck.org instead of receiving flowers.
