The body of Simon Foster, 40, was discovered in mid-April in his apartment in the Brighton, England, area, The Argus, a local newspaper, reported. Foster's death was announced Tuesday.

The television show touted Foster and his wife, Jane, for their alternative lifestyle when their show aired last year.

"The free-spirited Fosters are a family with a difference -- Jane and Simon both have girlfriends outside of the marriage," the show said.

But by the time the show aired, the couple had separated. Foster, who had been a truck driver, lost his job.

"Simon was a good man who loved his kids," a friend told The Argus. "He hit a bad patch after the divorce and started taking drugs. I'm sure his death was an accidental overdose."

RDF Media Group, which produces "Wife Swap," issued a brief statement offering condolences to Foster's family and saying that all those who appear on "Wife Swap" are offered counseling.
