Many famous stars once sat in their bedrooms singing along to someone else’s songs. Years later, a few of them got the chance to share a stage or a studio with those same heroes.
These stories show how early passion can turn into real opportunity. Here are eight collaborations that began with a young fan’s admiration.
1. Billie Eilish and Justin Bieber
Posters of Justin Bieber once covered Billie Eilish’s bedroom walls. She has said she was a devoted fan as a young girl, and that love stayed with her as she grew into a star herself.
In 2019, that admiration turned into a project. Bieber appeared on a remix of her hit Bad Guy, giving the track a fresh sound and bringing two generations of pop fans together.
Fun fact: Eilish was still a teenager when the remix came out, so she was working with the singer she had admired in middle school. The song reached a huge audience and showed how a fan moment can become a career highlight.
For young readers, the story is a reminder that big dreams can start in small places, like a bedroom full of music and a lot of imagination. Keep listening, keep practicing, and keep your heroes close.
2. Ariana Grande and Kristin Chenoweth
Long before she sold out arenas, Ariana Grande was a kid who loved Broadway voices. Kristin Chenoweth was one of the singers she looked up to most.
In 2016, the two shared a screen in Hairspray Live!, the televised musical event. Grande played Penny Pingleton, while Chenoweth took on the role of Velma Von Tussle’s world with plenty of sparkle.
Working side by side gave Grande a chance to learn from someone with years of stage experience. Chenoweth is known for her strong soprano and her sense of humor, both of which fit the lively show.
The pairing is a nice example of how mentors can shape young performers, even from afar. A kid watching a favorite singer today might be the next person to share a stage with them.
3. Tom Holland and Robert Downey Jr.
Picture a boy watching Iron Man in a movie theater and imagining himself in the suit. For Tom Holland, that daydream eventually came true in a surprising way.
Holland grew up a fan of the Marvel films and the hero played by Robert Downey Jr. He later joined the cast as Spider-Man and shared scenes with Downey, starting with Captain America: Civil War in 2016.
On screen, Downey’s Tony Stark acted as a mentor to Peter Parker. Off screen, Downey also offered friendly guidance to the younger actor during the busy production schedule.
Their bond became one of the most loved parts of the franchise. It proves that the characters we admire as kids can sometimes lead us straight into the story itself.
4. Miley Cyrus and Dolly Parton
Some kids have to wait years to meet their heroes. Miley Cyrus only had to look at her own family tree, since Dolly Parton is her godmother.
Cyrus grew up around Parton’s music and her warm, bold personality. As Cyrus built her own career, the two found many chances to work together on stage and in the studio.
They have performed duets, including a well-known version of Jolene, and have appeared together on television specials. Their voices are very different, yet they blend in a way fans enjoy.
Parton has often spoken about supporting younger artists, and Cyrus has said how much that guidance has meant to her. Their connection shows how family, music, and mutual respect can grow side by side over many years.
5. Dua Lipa and Elton John
Elton John’s songs have filled car radios for decades, and Dua Lipa heard them as she grew up. Those melodies helped shape her love of pop music.
In 2021, the two teamed up for Cold Heart, a dance track that blends pieces of several of John’s older hits. The result sounded both new and familiar, which helped it climb charts in many countries.
Lipa has said it was a thrill to hear her idol on a song with her name on it. John, known for lifting up new talent, welcomed the chance to bring his classics to a younger crowd.
The song also shows how music can travel across generations. A tune from the 1970s can become a party favorite again when fresh voices join in.
6. Ariana Grande and Brandy
Listen closely to Ariana Grande’s runs and vocal layers, and you can hear echoes of Brandy. Grande has often said she studied Brandy’s music from a young age.
That respect led to a special moment in 2024. The two joined forces on a remix of The Boy Is Mine, a song that carries the same title as Brandy’s famous 1998 duet with Monica.
Brandy has long been called the Vocal Bible by fans for her smooth, layered style. Having her on the remix felt like a thank-you from one generation to the next.
For listeners, the track is a good example of how influence works in music. Today’s stars borrow from the past, and the past gets a bright new spotlight in return.
7. Ed Sheeran and Eminem
A young Ed Sheeran once memorized Eminem’s fast, complicated lyrics, word for word. That practice helped sharpen his own sense of rhythm and storytelling.
Years later, Sheeran got to work with the rapper on River, a song from his 2017 album Divide. Eminem delivered a lively verse that matched the energy of the track.
Sheeran has shared that hearing his hero on his own song felt unreal. Eminem, in turn, praised Sheeran’s talent and songwriting.
The pairing was unusual, since one artist is known for acoustic pop and the other for rap. Still, it worked, and it showed that favorite artists can inspire very different styles.
Sometimes the best lessons come from songs you play on repeat.
8. Olivia Rodrigo and Avril Lavigne
Few songs capture teenage energy like Avril Lavigne’s Complicated. Olivia Rodrigo grew up listening to it, and its pop-punk spirit shaped her own songwriting.
In 2022, Rodrigo brought Lavigne on stage during her tour, and the two sang Complicated together. The crowd sang along to every line, and the moment spread quickly online.
Rodrigo has called Lavigne a big influence, and fans can hear that style in songs like Good 4 U. Lavigne has praised Rodrigo in return, saying she enjoys seeing a new generation carry the sound forward.
The duet is a happy example of how music circles back. A song from 2002 felt just as lively in 2022, thanks to a fan who never forgot it.
