After 28 years together, Kissbassist Gene Simmons and his Playboy Playmate girlfriend Shannon Tweed may finally make it official.

On Tuesday’s season finale of the couple’s A&E reality series, Gene Simmons’ Family Jewels, the rocker, 61, gets down on bended knee to propose to the mother of his two children.

“I come with so much baggage, but you’re the only friend I’ve got. You’re the only one I love…and you’re the only one I ever will love,” Simmons told Tweed during a recent vacation to Belize, according to advance show excerpts obtained by E! News. “I’ve never said those words to anybody. And I don’t ever want to…funny, I used to watch movies where they say I can’t live without you, but for me it’s true. Please marry me.”

While fans will have to wait until Tuesday’s episode to see if Tweed, 54, accepts, the rocker’s proposal is a definite deviation from his earlier views on marriage.

“Marriage means nothing to me. Happiness means everything,” he once said. “All I see in marriage is a lot of desperately unhappy people.”

On Twitter Monday, both Simmons and Tweed played coy as to if they’re engaged, though Simmons did post a telling message, proving that his love for Tweed is stronger than ever.

“Tomorrow night I put Shannon before everything,” he wrote in reference to his TV proposal.
