Rob Lowe has dabbled in meetings with mediums and psychics, and said he's found his late friend Bill Paxton in the process. On the Thursday, May 8 episode of SiriusXM's Literally! with Rob Lowe podcast, Lowe, 61, told guest Kelsey Grammer that Paxton, who died at 61 in 2017 due to complications from surgery, appears to him often in his sessions with a medium, as the two actors discussed their shared interest in mediumship and the paranormal. "Do you ever have people in your life that you think would come up in readings that just don't make as much of an appearance? For example, my mother rarely shows up. Rarely," Lowe admitted during the conversation. "And then I have the great actor Bill Paxton, who was a great friend, and that f------ guy is everywhere all the time." Lowe and Paxton costarred in 1991's The Dark Backward and 1994's Frank and Jesse. When Paxton died, Lowe was among the chorus of Hollywood stars who mourned him publicly, calling him "my close friend and one of the finest actors in the business" in an X post at the time. "He's everywhere," Lowe added with a laugh on Thursday, before he broke out his Paxton impression. "He's going, ‘Well, God, I heard you and Kelsey on that podcast. God, you guys are talking about everything.’ " "You know, I've thought about him some and thought about his energy and how it was probably a real surprise to be, 'What- what am I dead? What, what, what's happened here? You know, what, what the hell?' " Grammer responded.

"I don't know what he was [in surgery] for, but it was obviously a procedure that was not meant to end up in that way," he added of Paxton's sudden 2017 death. "I sure liked his work. I mean, he was so funny ... He was just a really, really terrific energy. And I dunno why that would disappear. Of course it didn't. So, you know I get that." Earlier in the conversation, Lowe said that one medium whom he has "talked to a bunch" felt his grandfather Bob and identified him by his interest in golf and penchant for greeting Lowe at the airport "with boxes of pies." The actor and podcast host also noted during the episode that his "late great manager," Bernie Brillstein, also tends to appear in his psychic reading sessions. "Bill said to me, he literally said to me, 'Buddy, I've been coming back and forth. I've been so busy,' " Lowe added, as he and Grammer speculated on the nature of death and whether there may be an afterlife.
