Adam Levine aint afraid to show his love for his wife Behati Prinsloo.

He proved it on their One-Year Anniversary as video has surfaced of the Maroon 5 frontman serenading his wife at Flora's Field Kitchen at Flora Farm in Cabo San Lucas, Mexico.

Although i'd find this a little too intimate and personal, he sang Marvin Gaye's "Let's Get It On" in front of the crowded restaurant on a little tropical island. And now Behati swoons as well as the world. But truth be told. I'm sure Adam comes home from filming The Voice at NBC and busts out in song all night long. She's probably used to it by now.

No, she'll never get used to it. She's married to Adam Levine dammit !! "Sing 'This Love' again Hubby !! Or I'm taking Half !!"
