Simon Cowell's new Netflix docuseries, The Next Act, opens with the music mogul getting what his partner, Lauren Silverman, describes as "the longest haircut ever" inside their sprawling London home. Just when she thinks it's finally over, an irritated Silverman, 48, walks back into the bathroom and asks Cowell, 66, why he's getting his "makeup done too," to which he deadpans, "To look handsome." Stars - They're Just Like Us, eh? Sure, the six-episode show (out Wednesday, December 10) features Cowell jetting from a sun-kissed Barbados villa to his crystal-filled Malibu mansion and a beachfront Miami hotel, but even during luxurious pit stops, he's as simple as they come. After all, the man's been wearing his signature black T-shirt and jeans for two decades and counting! "When I go to work, it's so easy," he says in Us Weekly editor-in-chief Dan Wakeford's new Just Like Us video series. "I just open up my wardrobe door, everything's identical, and I don't have to think about it." Those tees have been through it all with Cowell, who got his start in the music industry in the 1980s before becoming a household name in the early aughts as a judge on American Idol, The X Factor, America's Got Talent and their British counterparts. He's launched the careers of Little Mix, Fifth Harmony and, most famously, One Direction, but now he's on the hunt for a new group in The Next Act. Simon Cowell Kevin Winter/Getty Images "Since One Direction decided to split up [in 2016], I haven't signed another successful boy band," he acknowledges in the series. "I miss it so much."

Check out the biggest revelations from his Just Like Us interview below or watch the full episode above! Why He's Not Giving Up on Boy Bands Cowell could've retired off One Direction alone, but he's still passionate about finding a new group of young talent all these years later. "Of all the artists I've worked with, bands have always been my favorite," he tells Us. "It's a completely different dynamic working with a bunch of people compared to one person. I find it a bit boring working with one person. When we actually, hopefully find the band, you'll understand why I've done this, because the energy that it brings and the fun that it brings when it works, it's infectious. It's just brilliant. And I genuinely, genuinely miss doing it. And I thought, 'OK, if we're going to do it, we're going to have to do it now. Otherwise, I'll never do it again. And if we are going to do it, why don't we just show the whole process?'" Danny, Hendrik, John, Jack G. and Joe in "Simon Cowell: The Next Act" Netflix Returning to His Roots In the TikTok age, where any aspiring artist can blow up overnight from the comfort of their bedroom, Cowell sticks to a tried-and-true method in The Next Act: in-person auditions in London, Liverpool and Dublin showcasing contestants' real-life stories. "I think sometimes with these shows - and I've been guilty of this in the past - the show becomes more important than the people who come on the show," he tells Us. "And I don't feel that way on this. Without the people who enter, you have no show." Securing a Hit Cowell estimates in The Next Act that he's responsible for "more No. 1 records than anyone else in the music business" - some of which he's proud to say are still in his everyday rotation. "'What Makes You Beautiful' by One Direction is one of my favorite records I've ever put out," he says. "I was waiting, waiting, waiting for that record to come in. All the songs [I was pitched for the band], they just weren't there. And then someone said, 'A new one's coming. I think you're gonna like it.' I had just landed in Miami, and I asked the guy I was in the car with, 'Do you mind if I play the song?' I put it on, and I'll never forget it. I'm like, 'Christ, that is effing brilliant!' And also 'Bleeding Love' by Leona [Lewis]. Love that. I never get tired of those two." Simon Cowell Kevin Winter/ImageDirect Sizing Up the Competition Although he didn't discover Taylor Swift, Cowell keeps up with the biggest pop star in the world - Just Like Us! "She really knows who her audience is," he marvels. "She knows what a great pop record is. Incredibly smart. I have a lot of respect for her." AGT's Simon Cowell Reacts to Fans Who Think He's Softened as a Judge Realizing Money Isn't Everything When Cowell was in his 20s, he nearly went bankrupt from spending so much money. He ended up moving back in with his parents until he got back on his feet. "When you've lost your house, your car, everything, and you're still in debt, it's a real kind of like, 'Whoa.' Actually, it's not as bad as you think as long as you've got support around you," he tells Us. "I didn't lose any friends. My mom and dad were amazing. I managed to pay back what I owed. But I don't regret it because I now appreciate what I've got, and I've learned a lot o
