Beloved singer, songwriter, and actress Demi Lovato made her Stern Show debut to promote her upcoming remix album “Revamped” and reveal how and why a Disney-backed pop sensation goes about transforming themself into a rock star.

Paul Simon has won 16 Grammys, helped sell over 125 million records, and earned two separate inductions into the Rock and Roll Hall of Fame, but when the timeless troubadour made his Stern Show debut he seemed far less concerned with sales figures and industry accolades than with how his diverse catalog of genre-bending music has been shaped by those who enjoy it.

The 56-year-old CNN host and longtime “60 Minutes” contributor returned to the Stern Show to shine a light on topics ranging from his unconventional upbringing as the great-great-great-grandson of business magnate Cornelius Vanderbilt to the converted firehouse where he and his ex-boyfriend cohabitate and co-parent their two children. Cooper also clued listeners in on the state of his oft-scrutinized network and some of the many projects he has in the works, from the next season of his podcast “All There Is” to his latest biography about an ultra-wealthy family, “Astor: The Rise and Fall of an American Fortune.”

Schwarzenegger, who’s led a state of over 30 million people and starred in several of the biggest blockbusters in Hollywood history, didn’t sit down with Howard to chat about governance or film roles. He stopped by the show hoping to inspire listeners to better themselves, as others have inspired him. In his new book “Be Useful: Seven Tools for Life,” the Austrian-born icon shares the lessons he learned while conquering Hollywood, the world of bodybuilding, and politics.

The man, the myth, the bandana-clad legend Keith Richards has finally made his Stern Show debut, much to Howard’s satisfaction. The iconic Rolling Stones guitarist and some might say living embodiment of rock and roll opened up to listeners about his life, his love of music, and why, unlike his decades-long partner in rock Mick Jagger, he will never be knighted. The 79-year-old rock and blues pioneer also had plenty to say about “Hackney Diamonds,” the Rolling Stones first original album in nearly two decades and the band’s only one without founding drummer Charlie Watts, who passed away in 2021.

Rock, rap, and pop superstar Post Malone returned to the Stern Show, following the release of his brand-new album “Austin.” The 28-year-old recording artist, who has eight diamond certified songs to his name and two diamond crowns in his mouth, spoke to Howard about everything from his unwavering support of Bud Light to his burgeoning friendship with fellow music icon Taylor Swift. He also discussed his multi-million dollar Magic: The Gathering card, shared several stories about stage injuries and face tattoos, and even performed a couple of songs for Howard and his listeners live in the Stern Show studios.

Actor, musician, and longtime friend of the Stern Show John Stamos stopped by the studio on Tuesday morning with a head full of impeccably coiffed hair and a heart full of hilariously endearing anecdotes, many of which appear in his new book, “If You Would Have Told Me: A Memoir.” The 60-year-old Beach Boys drummer and “Full House” star has lived a uniquely charmed life, so it’s little surprise many stories from his memoir have already made a splash in the news, including a time when he got his heart broken by a cheating girlfriend.

Comedian and TV personality Chris Distefano stopped by the Stern Show to participate in the on-air segment “What’s My Freaky Fetish?” But before rolling up his sleeves and getting his hands dirty, the 39-year-old New York native told Howard all about his backstory, including previous relationships, his father the ex-convict, and the unusual road he traveled to become a successful comedian.

The legendary singer, actress, filmmaker, and philanthropist made her long-awaited Stern Show debut, connecting with Howard from her home in Malibu to deliver an epic interview in service of her equally epic new memoir, “My Name Is Barbra.”

Solo star and former Van Halen vocalist Sammy Hagar returned to the Stern Show, eager not only to bend Howard’s ear with wild tales from the heyday of hard rock but also to announce the creation of a brand-new supergroup featuring longtime bassist Michael Anthony, second-generation drum legend Jason Bonham, and guitar virtuoso Joe Satriani. The ferocious foursome – who next year will embark on a “Best of All Worlds Tour” — performed publicly for the first time in Howard’s studio, playing classic Van Halen tunes like “Right Now” and “5150” while also celebrating the music of trailblazers ranging from Jimi Hendrix and Led Zeppelin to Anthony and Hagar’s former bandmate Eddie Van Halen, who passed away in 2020 after a long battle with cancer.

The undisputed queen of country music and bona fide American icon made her Stern Show debut, connecting with Howard from her Nashville studio while flanked by guitars and a smattering of Dolly-branded paraphernalia, including her new book (“Behind the Seams: My Life in Rhinestones”) and new album (“Rockstar”).
