Justin Bieber T-Shirt: Eff Who?

Justin Bieber made an interesting fashion choice during an afternoon out in Los Angeles yesterday.
As seen below, the beloved singer donned a t-shirt that quotes Cee Lo Green's break-up anthem, "F-ck You." That single, of course, is dedicated to an ex-girlfriend and her choosing of another man. Is Justin sending a message about/to Selena Gomez? Or just giving a shout-out to Green?
And what's up with the Orlando Magic hat, JB?!? You're Canadian. The Toronto Raptors could really use some love right about now.
