Stephen Moyer and Anna Paquin, celeb couple and stars of the hit HBO series "True Blood," have joined their associated fan sites (allstephenmoyer.com, trueblood-online.com) to auction off their autographed original "True Blood" calendar for charity project Facing The Atlantic.

Facing The Atlantic is a bold side project in which actor Bertie Portal and trainer James Cash will participate in the Atlantic Woodvale Race and row nonstop from the Canary Islands to Barbados. Their goal is to raise approximately $482,000 U.S. for the Facing The World children's charity.

Facing The World is a UK charity that provides facial reconstructive surgery for children with facial disfigurements who don't have access to the resources and funds for treatment and care around the world.
