Jay Z and Beyoncé

As the music industry’s royal couple, Jay Z and Beyoncé share a particularly private relationship compared to many of their contemporaries, but their musical collaborations allow listeners the occasional glimpse into their personal lives. From Jay Z’s 2003 hit “03 Bonnie and Clyde” to Beyoncé’s 2013 smash “Drunk In Love,” the most influential duo in the entertainment business has released a dozen songs throughout the years of working collectively.

Their professional relationship predates their romantic involvement, but no matter their relationship status, they have always been best friends, and it shows. For example, the couple loves to surprise crowds by bringing each other out on stage during concerts to perform their iconic duets. During these special instances, Queen Bey cannot help but exchange her usual fierce facial expressions for warm smiles and loving glances toward her husband.

Dev Hynes and Samantha Urbani

Dev Hynes, the man behind Blood Orange, evidently loves to sing with his girlfriend Samantha Urbani of Brooklyn band Friends. She is featured in many songs from his 2013 album “Cupid Deluxe,” including “You’re Not Good Enough,” “It Is What It Is” and “Always Let U Down.” All of the songs on which they collaborate have an affectionate, conversational tone, further demonstrating the authenticity of both their relationship and their artistry. The couple clearly has an amazing on-stage chemistry when Blood Orange performs. Hynes and Urbani dance together, share smiles across the stage and hug while performing — much to the delight of their audience.

Win Butler and Régine Chassagne

For almost 10 years, married couple Win Butler and Régine Chassagne has fronted the band Arcade Fire. The pair of artistic geniuses met at McGill University in Montreal where Butler eventually convinced Chassagne to join Arcade Fire. Because of variance in the band’s line-up, at one point the two found themselves as the only members remaining in the group. The pair finally got married in 2003 and has accrued numerous musicians for Arcade Fire in the years since, including Butler’s brother William. In 2011, the band’s 2010 release “The Suburbs” won a Grammy for Album of the Year, and a couple who wins a Grammy together stays together.
