Gene Simmons proposes to Shannon Tweed, partner split after 28 years

The marriage proposal seen in previews for Tuesday night's finale of the A&E's "Gene Simmons Family Jewels" may be moot, according to rocker Simmons' longtime partner, Shannon Tweed, who says their 28-year relationship is over. "You're seeing this happy family but in my heart, I am dying," Tweed recently told People magazine.

The proposal -- in which Kiss bassist Simmons, 61, told 1982 Playboy Playmate of the Year Tweed, 54, "I come with so much baggage, but you're the only friend I've got, you're the only one I've ever loved" -- was taped months ago. Tweed told People that since then, she has moved from their Los Angeles home and there was "slim chance" for a reconciliation. "I need some sort of commitment," she said.

The show's past season has followed the couple and their children Nick, 22, and Sophie 18, through family therapy that focused on Simmons' infidelity.

Tweed has tweeted frequently about the issue, posting last week that, "he's NOT [a sex] addict! He's a spoiled rockstar who lied about being faithful."

Simmons' manager could not be reached for comment. An A&E spokesman told Newsday: "Gene and Shannon's relationship is a complex one that is constantly evolving with upswings and downswings. We have documented those swings accurately as they occurred."
