Tweed later posted Twitter messages about the episode, saying: "I love you all!!! See you in the fall!!!! Trust me. It was the hardest decision I ever had to make. My whole life flashed before my eyes. Did you see how long I stood there? Mind racing.."

Tweed said on the season premiere of "Gene Simmons Family Jewels," which aired in June, that she was tired of Simmons' "wandering eye." The rocker has famously claimed to have bedded some 5,000 women.
