Luke Bryan says that Blake Shelton should marry Gwen Stefani as soon as humanly possible.
In an exclusive interview with ET's Nancy O'Dell at the 2018 Academy of Country Music Awards in Las Vegas on Sunday, Bryan offered to even marry the couple amid rumors of wedding bells being in the future.
"I'll do the sermon. The sermon? The service?" Bryan said. "I would be honored to marry Blake and Gwen."

Gwen Stefani Addresses Rumors She and Blake Shelton Are Getting Married
"If Blake were smart, he would marry her before she goes to an optometrist," he said, grinning from ear to ear. "Every time I meet Gwen, she's holding her phone way out here. I'm like, 'That's it, she can't see!'"
Bryan, now a judge on American Idol, got some additional good-nature digs in on his friend Shelton. The two have ribbed one another relentlessly, with Shelton saying people watching the show "are going to realize just how dumb he [Bryan] really is."
"Well, Blake's got a few years on me, but my intelligence is far superior than his," Bryan said on Sunday. "So, yeah, I think I got him. I need some more competition."
Speaking of competition, Bryan was nominated for Entertainer of the Year on Sunday, an honor he took very seriously.
"You never take it for granted, always certainly humbled and honored by it," he said. "It'll be a fun moment to see who wins -- it's always fun to see what face you'll make if you don't win."
He continued, "It's an emotional ride. We work hard -- I work hard out here -- all of us country artists. We work hard on the road, and any time we get recognized for it it's pretty emotional."
