Las Vegas ? Singer-actor-impressionist Danny Gans, who spent more than a decade as one of the most popular entertainers in Las Vegas, died Friday. He was 52.

Gans was pronounced dead in his bed shortly after police and paramedics were summoned to a report of a man not breathing at Gans’ home about 3:45 a.m., said police spokesman Todd Rasmussen.

Foul play was not suspected, Rasmussen said. A Clark County coroner’s spokeswoman said an autopsy was pending, and Rasmussen said police were investigating “according to standard procedure.”

Gans’ manager and longtime friend, Chip Lightman, said Gans was in good health but slept poorly after Wednesday’s show and took a nap late Thursday afternoon, a day off. He stayed in bed into the evening, and his wife, Julie, summoned police when she couldn’t rouse him after 3 a.m.

“This makes no sense,” said Lightman, who said Gans didn’t use illegal drugs, didn’t smoke and had no apparent medical issues. “I managed him 18 years and health was never an issue.”

Gans was mourned by two Las Vegas entertainment legends, Siegfried Fischbacher and Roy Horn.

Like Gans and Wayne Newton, the careers of the German duo became synonymous with Las Vegas after they brought their acts to the Strip.

“We were blessed to be touched by his generous spirit, kind heart and insurmountable talent,” Siegfried & Roy said in a statement.
