Dan + Shay and Justin Bieber let their wives co-star in the music video for "10,000 Hours," their collaboration on the country duo's upcoming album.

Dan Smyers' wife Abby, Shay Mooney's wife Hannah and Bieber's wife, Hailey Baldwin, sit along their husbands in the just-released music video. The three men spend significant time singing to and fawning over their brides during a love song that describes an aching for a long-term romance.

Bieber wed Baldwin in front of friends and family on Monday (Sept. 30), and the two country singers were there. In fact, they even performed!

Mooney and Hannah Billingsley were married in 2017 and will soon welcome their second child together. Smyers and Abby Law also married in 2017. Dan + Shay had a breakout year in 2018 that has continued through 2019. They're among the most nominated acts at the 2019 CMA Awards, to take place in Nashville on Nov. 13.

Speaking to Taste of Country, Dan + Shay explained the meaning of the title of the song and revealed that they had Bieber in mind from the very start. They reached him through their mutual manager.

"He hit back right away like, '(He) loves the song. Wants to do it,'" Smyers shares. "So we connected and he wrote a couple of lines on it, put his spin on it."

"10,000 Hours" was one of three songs Dan + Shay performed at Bieber's wedding, along with "Speechless" and "Tequila." The duo said they'd not been contacted about a potential CMA Awards performance, but played coy when asking about a potential tour with Biebs.
