Bruno Mars was spotted lugging a huge piano through a dark, wet tunnel in Los Angeles Monday afternoon (Oct 11). The R&B singer was filming a scene for the music video for his latest single “Grenades.”

Mars’ debut album Doo Wops & Hooligans hit stores last week and sold 55,000 copies, putting him at #3, behind Toby Keith (71K) and Kenny Chesney (65K), on the Billboard 200 albums chart.

What do you think about the pic and Bruno’s album sales?
