What do you think?  Will Gene Simmons and Shannon Tweed ever get married?  ~Erin

You can't always believe what you see on reality TV. Case in point: KISS bassist Gene Simmons finally proposed to longtime girlfriend Shannon Tweed. Turns out, the proposal scene in Tuesday night's finale of A&E's reality show Gene Simmons Family Jewels was taped "several months ago," a source confirmed, and it's been a rocky road for the pair ever since.

Simmons, 61, and Tweed, 54, were vacationing in Belize when he proclaimed, "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," before getting down on one knee.

It remains to be seen whether Tweed will be saying "I do" and sticking with it. She did, however, tell PEOPLE in a recent interview that she had moved out of their home and that there was a "slim chance" of them getting back together. "You're seeing this happy family," Tweed said, "but in my heart, I am dying."
