Since the first time I heard him on B.o.B.'s "Nothing on You" I've always thought Bruno Mars was super-talented.  In the past I've brought you some unexpected covers Bruno has done live (my favorite of which being this cover of "Under the Sea" from The Little Mermaid), but this one MAY take the cake.


Check out this mash-up of cover songs Bruno pulled out at a concert.  It includes Nirvana's "Smells Like Teen Spirit," Michael Jackson's "Billie Jean," and the White Stripes' "Seven Nation Army"!
