"The Voice" coach Adam Levine proved that he's every bit the "sexiest man alive" when he serenaded wife Behati Prinsloo on their wedding anniversary with Marvin Gaye's bedroom song, "Let's Get it On."

Adam Levine and Behati Prinsloo tied the knot on July 19, 2014 in Cabo San Lucas, Mexico in front of their families and closest friends.

On their wedding anniversary, the couple traveled back to Cabo to celebrate.

"The couple was enjoying dinner at Flora Farms last weekend-the same location where they got married last year-when Levine suddenly took the stage and began serenading his supermodel wife with a sexy rendition of Marvin Gaye's hit "Let's Get It On" in front of a throng of onlookers," said the report.

After the impromptu performance of the sexy song, Adam Levine then gave his wife a lingering kiss on the lips to the delight of the people surrounding them.

Adam Levine just debuted his new bald look on Instagram as he wrote, "She's into me...I think..."

In a previous interview, "The Voice" judge Adam Levine said that he's very happy about being married to Behati Prinloo.

"I never really thought I would adore it. It's so trippy. I'm a child," he said. "How did this happen? I use that word [wife] right now a lot. I say it for no reason. I say it a lot - 'Wife wife wife,' I love it. I even changed her number in my phone to 'Wife.'"

For her part, Behati Prinsloo told Extra that she loves being domesticated after marrying Adam Levine.

"I feel great. It's just a solidness. You're with the person you should be so it's a very comforting, amazing feeling," the Victoria's Secret model said. "I've been taking cooking lessons, I've been making roast chicken from everything. My favorite thing is chicken noodle soup... It's been fun. Domesticated."
