He’s always been easy on the eyes, and Adam Levine gave his model fiancée Behati Prinsloo an impromptu strip tease show this week.

The gorgeous Victoria’s Secret model posted a photo of her Maroon 5 man wearing only his underwear along with the caption, “70’s porn called. It wants its vibe back. Immediately.”

Levine credits his Yoga regimen with keeping him in such great shape, both physically and mentally.

He told press, "I have a hard time sitting still. I can be all over the map. Yoga has given me the ability to be more focused and make better decisions that come from a clear place. It's made me more successful. I love it and don't know what I'd do without it."
