Watch Bruno Mars Singing At His Brother's Wedding Before He Was Famous!

Back in 2007 Bruno Mars was only 22 and his older brother, Eric, was getting married. Bruno was his brother's best man and he dedicated to serenade the wedding couple to Alicia Keys’ “If I Ain't Got You.”

Typically the guests at the wedding are focused on the couple during their first dance but not in this case! They were all focused on Bruno and his amazing voice!

It wouldn’t be until three years later when Bruno dropped his first hit “Just the Way You Are.”
