LOS ANGELES (REUTERS) - Olympic champion and reality television star Bruce Jenner has been sued for wrongful death by relatives of the woman killed in a car crash involving the former athlete on a Malibu highway in February, a Los Angeles court spokeswoman said on Friday.

Spokeswoman Kathy Roberts said the 16-page lawsuit was brought by two stepchildren of Kim Howe, who died in the Feb 7 four-car collision on the Pacific Coast Highway that sheriff's deputies said at the time left five other people injured.

Jenner, an occupant and the presumed driver of one of the vehicles, declined medical treatment at the scene, authorities have said.

Jenner's publicist, Alan Nierob, said of the lawsuit, "At this point we have no knowledge of this, and have no comment."

The suit came one week after Jenner declared in a nationally televised interview that he identifies as a woman, becoming the most high-profile American to come out as transgender.

A publicist, however, has said Jenner still prefers to be referred to with male pronouns.

Jenner, 65, rose to fame with a record-breaking Olympic gold medal victory in the decathalon in the 1976 Summer Games in Montreal that earned him the unofficial title of "World's Greatest Athlete."

Known to younger generations as the patriarch of reality TV's Kardashian clan, Jenner appeared on ABC's 20/20 last Friday to put to rest months of speculation that he was transitioning to life as a woman.

The interview was conducted before the Malibu car crash.

The accident remains under investigation by the Los Angeles County Sheriff's Department.
