Pregnant actress Jaime King and Glee actor Chris Colfer were among the stars who gathered at GEORGE LUCAS' California ranch on Tuesday (09Jul13) to kick-off a charity relay race.

The Sin City beauty and her husband Kyle Newman wore Star Wars inspired T-shirts for the Course of the Force run, while Colfer completed his dash with a Chewbacca-style puppet strapped to his back.

Model/Tv star Adrianne Curry and actor Alexis Denisof also took part in the first day of the 500-mile (804-kilometre) run, which is staged to celebrate the sci-fi franchise ahead of San Diego's annual Comic-Con International convention and raise money for the Make-A-Wish Foundation, an organisation which grants wishes to children with life-threatening medical conditions.

In a post on his Twitter.com page after the run, Colfer told fans, "So excited to have been a part of the Course Of The Force relay for the Make-A-Wish Foundation!"
