DEBB Eaton, the controversial first castoff from “Survivor II” known for romancing her stepson, said on yesterday’s “Early Show” that she has no regrets about that decision.

“It’s not immoral and you don’t choose who you fall in love with,” Eaton told Bryant Gumbel.

Eaton, a 45-year-old New Hampshire corrections officer, made headlines when it was revealed that she was planning to marry her 34-year-old stepson, Bobby, after his father, a state trooper, died three years ago.

“No, I’m not getting married and I’m not engaged,” Eaton told “Inside Edition” in an interview that airs today (9:30 a.m. on Ch. 2).

“But [Bobby] is the best thing that ever happened to me.”

Meanwhile, CBS is upping the ante – again – by repeating Sunday’s “Survivor II” debut tomorrow from 8 to 9 p.m. – just before a new episode of Fox’s red-hot “Temptation Island” at 9 p.m.

On yesterday’s “Early Show,” Gumbel broached the stepson subject after a bit of small talk about Eaton’s “Survivor II” experiences.

“You’ve been splashed across the tabloids lately . . . for what some would see as an immoral, unethical, romantic relationship with your stepson,” Gumbel said.

“Obviously you don’t think it out of line, you don’t have a problem with it. Why not?”

“I was with a man for 20 years who I loved very much. He died. I fell in love with somebody else,” Eaton said. “I never had a mother-son relationship with Bobby.

“That never happened,” she said. “And we share a love and commitment to each other that as far as I’m concerned is a gift from God – and no one’s going to make me feel bad about it.”

“So although Bob is your stepson, you were never a mother to him?,” asked Gumbel.

“Never, never,” Eaton said. “I was 22 years old when I first met Bob. I had my own son. You know, I was a bad step-parent. I will admit that and I have apologized for that because I never had room in my life for two teenaged boys.

“But no, I was never a mother to Bob.”

Eaton told Gumbel she thinks she was voted off the show because she refused to participate in an “X-rated” conversation inititated among members of her tribe, the Kuchas (Aborigine for “kangaroo”). The other tribe is the Ogakors (“crocodiles”).

“I think I was my own worst enemy when it came right down to it,” she said. “We had some conversations. They were kind of X-rated and, in my perspective, they were intrusive. And it kind of separated me from the tribe right off the bat.

“You know, what happened is I separated myself simply because of the conversations,” she said. “I didn’t fit in and then the last day, I thought that I was dead. I thought that everyone had already decided against me.

“And then I separated myself further and I did myself in.”
