Like Taylor Swift and Joe Alwyn, These 10 Couples Wrote Hit Songs Together

Taylor Swift and her current boyfriend, Joe Alwyn, worked together on a handful of songs on her albums "Folklore" and "Evermore," including "Exile." Writing under the name William Bowery, Alwyn helped Swift pen songs that were a bit of a mystery to fans until she revealed the truth. Alwyn told Vulture in early May that he found himself walking around the house during COVID singing and tinkering at the piano — which eventually became "Exile." "It was completely off the cuff, an accident," he said of writing "Exile." "[Swift] said, 'Can we try and sit down and get to the end together?' And so we did. It was as basic as some people made sourdough."

"If the World Was Ending" was the very first song JP Saxe and Julia Michaels wrote together. When they initially linked up to write the song in 2019, they'd never met before — but ended up falling in love. Michaels told Entertainment Tonight in March 2021 that Saxe is one of her favourite songwriters. They went on to pen more songs together, but it's unclear if Michaels and Saxe are still together.

Shawn Mendes and Camila Cabello penned "Señorita" together in 2019 — right before the official announcement that they were a couple. It was the second track they'd written together, following "I Know What You Did Last Summer" in 2015. The song took a long time to come together, according to Billboard: a group of songwriters started working on it in 2018, and when they brought Mendes in and told him the song should be a duet, he said "the only person" he'd do the song with was Cabello. While the song (and their relationship) was certainly steamy, Mendes and Cabello broke up in fall 2021.

Halsey and Yungblud's song "11 Minutes" arrived on the airwaves in 2019 while the two were dating. Yungblud told NME in March of that year, "Me and Halsey met for a drink just to talk about music, and to be honest, man, that never happens. Everyone's always wanting to see what they can get out of you. I was a massive fan of hers; she said she was a big fan of me, so I was like, 'Woah, that's cool.' We just met up, and we realised we had so much in common." This makes it sound like they wrote the song together before they even started dating (they began dating sometime near the end of 2018). They broke up in 2019.

Before Mac Miller and Ariana Grande started dating, they wrote "My Favourite Part" together, according to People. It was the third track they'd worked on together. "I wrote that love song before I saw her. We're very good friends, first and foremost," Miller told People in 2016. "We made that song and started becoming close again. It's very dope, and I like how that worked out." The two ended up getting together officially soon after that but broke up in mid-2018, just months before Miller died from an accidental overdose.

John Mayer and Katy Perry worked on "Who You Love" amid their on-again-off-again relationship (which went from 2012 to 2015). Released in 2013, "Who You Love" shows the two sides of being in love. Mayer told Billboard in 2013 that the root of the song is "I love you based on the fact that I've tried to run, and I'm not running, and I give up." He added, "I immediately thought about Katy, and I was like, what a cool voice. What a cool artistic personality to have on. It was a really fun opportunity for her to write, like, her answer to that. So you get these two sides to this relationship that are brutally honest but no less universal."

Beyoncé and her husband, Jay-Z, have worked on a number of tracks together; the very collaborative couple even tours together. The two copenned "Crazy in Love" in 2002 for Beyoncé's debut solo album not too long after they'd started dating. Producer Rich Harrison, who first brought the beat to Beyoncé, told MTV in 2004 that the whole project started while he was hungover, and he wasn't sure the former Destiny's Child singer was even going to like what he was offering. But he worked with her for months on it before Jay-Z came in and laid down his rap in just a few hours, giving birth to one of the greatest songs of the century.

When Avril Lavigne started working on her album "Love Sux" in 2020, she was single. But then she met Mod Sun, who cowrote several of the album's tracks with her, and the two ended up dating and eventually got engaged. One track they wrote for the album is "Love It When You Hate Me," which also features Blackbear. Lavigne has spoken warmly of her fiancé and his musical abilities, telling Us Weekly that he's a "really incredible songwriter."

Meek Mill and Nicki Minaj cowrote "All Eyes on You," which was released in 2015 — several months after they started dating. The track, which alludes to the couple's first meeting, was just one piece of the couple's intense relationship. Despite how hot and heavy they were for much of their relationship, it fizzled out: Minaj confirmed their breakup in 2017.
