Pharrell Williams started off his performance of 'Happy' at the 2015 Grammy Awards tonight in the absolute most serious way. We were kinda freaked out, tbh.
You no doubt remember the smash hit of last summer, "Blurred Line" by Robin Thicke and Pharrell. What you might not realize is last year Marvin Gaye's children sued Robin Thicke because they claim it's a rip off of their father's song.
