Chapman and her husband Duane "Dog" Chapman starred in the A&E show until it was canceled in 2012. "She is in another place", Dog said.
Duane Chapman reminisced about how he and his wife first met and his grief.
He added: "I went in and she said, 'Look at me.' And I said, 'Yeah, you're freaking lovely baby.' (And she said, ) 'Look at me, Duane Chapman.' And I did, I always saw Beth and she said, 'Please, let me go'".
"She believed in God very much", he said, then broke down, crying, "I can not believe that she's gone". "This is not possible, I want to wake up from a dream".
The memorial also included short speeches from Gene Simmons' wife Shannon Tweed, plus Beth's sons Dakota Chapman and Gary Chapman and daughter Bonnie Chapman.
"I hugged him and I felt a connection like, boom, instantly brotherhood, right", Chapman explained.
She added, "And she's not here right now but I'm definitely going to miss her laugh-that's something that when it did come, it was like bells, and it really made the whole family happy". Cameras were present to capture both services; the couple were filming a new show for WGN called Dog's Most Wanted at the time of her death, with her cancer battle as a central plotline. He recalled saying his prayers as a child, speaking softly to his wife as he said, "Bethie, now I lay you down to sleep", as his voice cracked again.
She also shared a touching tribute to her mother, writing: "I'll never forget you, mama". Because she always wanted people to know what happened if they go on her dark side'. "I'm not gonna let you go.' I still haven't let her go", he said, later adding, "If there's a God, He won't let me live that long without her".
"I walked through the closet the other day and I smell her", he tearfully said. And I'm one of them.
"I'd never thought I'd lose my mom at 20", she wrote.
She also shared a photo of her parents smiling, and captioned the post: "So thankful I got your handsome smile".
Tweed laughed and admitted Beth could, "throw me like a rag doll".
