Last year, the 79-year-old game show host made the somber announcement that he was diagnosed with Stage 4 pancreatic cancer. Although he has voiced no official retirement plans in the midst of his health battle, he’s joked that in the event that he does step back, he wants pop culture favorite White, 98, to replace him.

“I joke with the audience all the time and I say, ‘Betty White,’ because they want somebody younger, somebody funnier,” Trebek, who turns 80 Wednesday, told “Good Morning America.”

White is a longtime pal, and over the years, the two have shared banter and fun flirtation. In 2018, White told The Post that she enjoys watching “Jeopardy!” because, “First, it’s such a good game and, second, I happen to have a huge crush on the host, Alex Trebek.”

White has been in the biz even longer than her celeb infatuation — for a whopping 70 years. She’s best known for “The Mary Tyler Moore” show (1973-1977), “The Golden Girls,” (1985-1992) and “Hot in Cleveland” (2010-2015). And she hasn’t slowed down in her silver years, as she’ll star in an upcoming Lifetime Christmas movie, which is currently untitled.

Trebek has hosted the long-running “Jeopardy!” since 1984, and is contracted through 2022. He has a new memoir, “The Answer is . . . : Reflections on My Life,” out Tuesday.
