Back in 2009, Robin Thicke performed for then-Bachelor Jason Mesnick, who took Jillian Harris to see the artist perform in an empty venue. A mere four years later, his "Blurred Lines" single released in 2013, which shot him straight to the top. He's since worked with huge names in the industry, including Nicki Minaj, Mary J. Blige, and Christina Aguilera.
