Call Her Daddy host Alex Cooper revealed why Hailey Bieber picked her podcast to tell all

Alex Cooper has a very short criteria when it comes to inviting guests onto her podcast, .

"All I ask is people just be vulnerable and honest," the 28-year-old told a news publication ahead of the second season premiere of her wildly popular Spotify show, which in addition to the raunchy relationship talk listeners expect features candid sit-downs with the likes of Rachel Bilson, Miley Cyrus and -- in what was cheered as her most revealing interview to date -- Hailey Bieber.

"Sometimes people aren't ready to do that," Cooper added, "and I've had people circle back around months later and be ready. It really is just a give or take of where they're at, but I do think that Call Her Daddy now has this expectation of, 'Let's keep it real.'"

Besides, said the host who was one of Spotify's most streamed podcasters of 2022 (second only to Joe Rogan), she owes it to her loyal fanbase -- the "Daddy Gang," who's been with her "since day one," she explained. "I've got to provide them with entertainment while also respecting my guests."
