Take a look back at the record-breaking tour
Jessica Simpson and Nick Lachey were together for several years and recorded several duets. When they recorded 'Where You Are' (2000), they had been dating for two years.
The musicians allegedly dated briefly in 2009. During this time, they collaborated on the track 'Half of my Heart,' which then featured on Mayer's 2010 album 'Battle Studies.'
The song was also released as a single and it sold just shy of one million copies. The pair didn't stick together after 'Camp Rock' was over, but they are still good friends.
Although they never actually confirmed their relationship, they performed together at Z100's Jingle Ball in 2009, and Swift released the breakup song 'Dear John' later in 2010.
Rihanna and Chris Brown first dated from 2007 to 2009 and broke up following the high-profile domestic violence incident that year. In January 2013, Rihanna confirmed the relationship was back on.
The couple was married in 2004 and they toured together in 2007 before they parted ways in 2011. Even after they separated, they continued to collaborate on their music.
Rihanna clearly likes to make a habit of working with her boyfriends: she also recorded duets with her rumored boyfriend Drake while they were together.
Musical couple Nas and Kelis were married for five years, from 2005 to 2010. They collaborated on a number of tracks and performed together a lot during that time.
Their duets include 'In Public' (2005), 'Blindfold Me' (2006), and 'Not Going Back' (2006). Kelis filed for divorce in 2009, citing irreconcilable differences.
The pair married in 2002 and had a number of joint musical pursuits before they split in 2005. In particular, they did a cover of the Christmas classic 'Baby, It's Cold Outside' (2004).
Derulo and Sparks parted ways in 2014. Since then Sparks got married, and both musicians have had children: Sparks' son was born in 2018, and Derulo's in 2021.
Wiz Khalifa and Amber Rose started dating in 2011 and were married in 2013. They have a son together, Sebastian Taylor, who was born in 2013.
They collaborated on a track for her album 'Unapologetic' (2012). But by May 2013, Chris Brown confirmed in an interview that the two had broken up again.
The couple co-wrote the song for Mayer's album 'Paradise Valley' (2013) and appeared in the music video together. It wasn't meant to be, however: they parted ways less than a year later.
John Mayer has dated a number of other famous women in music, including Katy Perry. They released the duet 'Who You Love' together in 2013, after dating on and off for a year.
Jason Derulo and Jordin Sparks dated for three years. Together they recorded the song 'Vertigo,' which appeared on Derulo's 2013 album 'Talk Dirty.'
'Camp Rock' stars Joe Jonas and Demi Lovato briefly dated during their Disney days. Together they recorded the song 'This Is Me,' which featured on the 'Camp Rock' (2008) soundtrack.
Most famously, they worked together on 'What's My Name' (2010), but Rihanna also featured on Drake's 'Take Care' (2012). They reportedly split in 2016.
Miller also featured on a remix of Grande's 2016 single 'Into You.' The couple split in 2018, just months before Miller would die tragically from a drug overdose.
Halsey did vocals for G-Eazy's single 'Him & I' while they were dating in 2017. She even tweeted, "this song is so special to me. i made it with someone i love for the people we love."
Mac Miller and Ariana Grande first started dating in 2016, three years after their first collaboration on 'The Way' (2013). While together, they recorded the duet 'My Favorite Part' (2016).
The relationship between Jennifer Lopez and Marc Anthony started in music. They first met during the 1990s, and they recorded the duet 'No Me Ames' in 1999.
The couple broke up in 2018; the suggestion is that the relationship came to an end because he cheated. Halsey's breakup song 'Without Me' went platinum.
Ashley Frangipane (Halsey) and Dominic Harrison (Yungblud) dated for a very short time during 2019, but they did manage to fit a duet into that time.
The music video, which was shot by Director X, tells the story of when the couple met. Their relationship wasn't meant to last, though. Since 2016, Ciara is married to Russell Wilson.
The couple worked together on the track 'Never Been (Part II),' although granted Rick Ross also featured. Rose filed for divorce in 2014, citing irreconcilable differences.

Although Ciara's song 'Body Party' (2013) was not a duet, her boyfriend at the time and baby daddy, Future, provided ad libs and backups. He also featured in the music video.
They worked together on the rock duet '11 Minutes' (2019), which they also performed at the iHeartRadio Music Awards.
Although onstage chemistry would have us believe that singers who duet together, particularly when it comes to romantic duets, have feelings for each other in real life, more often than not this is not the case. But it does sometimes happen. In fact, there are plenty of examples of real-life couples who have collaborated on their music and recorded duets.
In some cases, those couples are still together and they can look back fondly on their successful work together. In other cases, however, the relationship has come to an end and the duet is all that remains.
