The hot couple wed on 19 July 2014 in front of 275 family and friends at Floral Farms in Los Cabos, Mexico, after two years of dating.

Behati wore a custom-made Marchesa gown to exchange vows with The Voice judge, watched by guests including Robert Downey Jr, Candice Swanepoel, Jonah Hill and Jason Segel.

The couple made their first red carpet debut together in October 2012

One month after their lavish wedding ceremony, Adam revealed that he and his wife were eager to start a family. "We’re definitely going to do it," the You Will Be Loved singer told Ryan Seacrest during an interview on KIIS FM radio. "I want to have 100 kids. I want to have more kids than would be socially responsible."

Being a mom has also been a dream of Prinsloo’s. Before she wed her rockstar husband, the Namibia-born beauty told NET-A-PORTER’s The Edit that she had "definite" plans to have kids with her man.

The pair began dating in June 2012 and made their official red carpet debut as a couple the following October at the GQ Gentlemen's Ball in NYC. "She makes me the best person I can be," he said of Prinsloo at the 2014 Tribeca Film Festival. "She's the best in the world."
