Emilie de Ravin, who plays Claire Littleton on ABC’s “Lost,” has separated from her husband after six months of marriage, her spokesman said Wednesday.

The 25-year-old Australian actress and actor Josh Janowicz, also 25, were married in Melbourne in June, publicist Jeff Raymond said. It was the first marriage for both. They have no children.

Besides “Lost,” de Ravin’s credits include the horror film “The Hills Have Eyes” and TV’s “Roswell.” Janowicz appeared on TV’s “Cold Case” and was the “hot priest” in the 2003 movie “Charlie’s Angels: Full Throttle.”

Emilie de Ravin, 24, who plays Claire Littleton on the ABC hit series Lost, wed actor Josh Janowicz on June 19, wearing a wedding gown by designer Monique Lhuillier. For her walk down the aisle, de Ravin wore a two-piece ivory Chantilly lace scoop neck top with cap sleeves, paired with a satin paneled trumpet skirt and accented with a cameo ribbon sash.
 
The couple dated for three years before becoming engaged on January 1, 2005, while visiting de Ravin’s family in Australia for the holidays.
