The married costars are helping raise funds for four children, ages 8 to 19, who found themselves parent-less when their mother and father died within months of each other last year.

The TV couple found out about the Darnell family when a mutual friend informed them about their plight.

The four Darnell children lost a sibling and were left orphaned on August 30, 2010 when their mother, 43-year-old Missy Darnell and Genevieve Darnell, their 10-year-old sister, were struck and killed by a car while walking to a local convenience store. The children had lost their father eight months prior.

The True Blood fan site SimplyMoyer.com has organized an eBay auction for the script. It starts Valentine's Day Monday, February 14th and ends on Wednesday, February 23.

Stephen and Anna were happy to help, even posing for an exclusive photo holding the autographed script.

The acting pair have already raised $2,280 for the Darnells from a previous auction last October.

The script they are donating this time is from episode 3.12, "Evil Is Going On", and is signed by Moyer, Paquin, and true Blood creator Alan Ball.
