From the moment Blake Shelton and Gwen Stefani began dating in 2015, many have looked at the country singer and pop star as a bit of an odd couple. Yet, leave it to Luke Bryan to put his finger on the magic between the two.

"Every time I meet Gwen, she's holding her phone way out here. I'm like, 'That's it, she can't see!'" Bryan told Entertainment Tonight’s Nancy O’Dell with a laugh during the ACM Awards on Sunday (April 15.) "If Blake were smart, he would marry her before she goes to an optometrist."

Bryan loves to rib his pal, Shelton. During the same interview, the "Most People Are Good" singer even volunteered himself to play some part in Shelton and Stefani’s possible future wedding. "I'll do the sermon. The sermon? The service?" Bryan said. "I would be honored to marry Blake and Gwen."

Bryan also ribbed his buddy when O'Dell asked who is a better reality TV personality. Shelton is a longtime coach on The Voice, while Bryan is in his first season as a judge on American Idol.

"Well, Blake's got a few years on me, but my intelligence is far superior than his," Bryan said. "So, yeah, I think I got him. I need some more competition."

All jokes aside, Bryan has had quite a  year in 2018 thus far, including grabbing an Entertainer of the Year nomination at this year’s ACM Awards, where he also performed. Jason Aldean ended up taking home Entertainer of the Year.
