Oprah Winfreyisn't joining her bestieGayle Kingby going to space any time soon. The ex-"Oprah Winfrey Show"host got candid on the July 16 episode of the SiriusXM show"Let's Talk Off Camera with Kelly Ripa"about why she skipped going on the infamous Blue Origin flight in April with her BFF. "I would never do it, but I became very interested in the whole process," Winfrey said. The Oprah's Book Club creatortold Ripa that she was "just so proud to be there for" King, adding she was "relieved" that the "CBS Mornings" host went to space, "because if she'd asked one more time, 'What should I do? Do you think I should go?' I, from the beginning, was like, 'You should do it.'" Winfrey also revealed that she told King not to "letKaty Perrycome down and say, 'It was really great fun.'"

However, the flight fromBezos-backedexploration company Blue Origin garnered widespread criticism. Still, Winfrey encouraged King to adventure. "You're going to be really saying, 'I should have done it,'" she recalled telling King. "The minute somebody says, 'Oh my God, like a life changing experience,' you're going to go, 'Oh, I should have done it.'" Oprah says July book club pick hookedher 'until the very last shocking sentence' The "Oprah Winfrey Show" star confessed that she knew it was time to leave her eponymous daytime talk show, which ended in 2011, when her team suggested they send an audience to space. "I remember going into a meeting and someone saying, 'I think what we should do is try to get people on a spaceship, or we should be able to take an audience or some audience members up on a spaceship,'" Winfrey said. After making the admission, Winfrey gave her fellow talk show host a word of advice and told her that "it's not time for you to step away" from "Live," which Ripa hosts with husband andactor Mark Consuelos, because "you have fun and it's easy and it's light enough. And serious enough when it needs to be, and it's not a grind." The "Oprah Podcast" host said that she loved hosting her own show, but it was different than Ripa's because the "Oprah" show dealt with heavier topics, sharing with the "All My Children" alum that "the nature of what we were doing every day became just so hard."
