Leave it to Pharrell to get creative with his performance!
The 41-year-old singer celebrated his actual birthday in a fantastic way: by singing on Saturday Night Live!
And to make sure it was extra special, he had a little help.
First, Pharrell sang his well-known hit Happy, but then he brought out Hans Zimmer and a string orchestra for the performance of Marilyn Monroe.
As usual, he was wearing that hat too…
LOVE the performances, but could have done without the topper! The music is absolutely worth a listen though
