A funny video of a three-month-old baby who appears to be Bruno Mars' youngest fan.

The footage, filmed in Fayetteville, North Carolina, USA on May 2, shows little Maximus crying whenever he hears a song... unless it's Bruno Mars, who he seems to like.

"If you look closely, at one point he even begins to drool because he is so mesmerized by Bruno Mars," the filmer added online.

3 month old Maximus is Bruno Mars' youngest fan. Even though he is a baby, he knows good music when he hears it. He continues crying with any other artist but when he hears Bruno Mars, he instantly stops as you can see in the video. If you look closely, at one point he even begins to drool because he is so mesmerized by Bruno Mars.
