Fallon and Bieber sneaky in NYC

In what appears to be a segment being filmed for The Tonight Show, Justin Bieber and Jimmy Fallon donned some not-too-effective disguises to pal around in the park on Tuesday afternoon.

The two were spotted filming a sketch in NYC wearing wigs and suits. Sources speculate that the Tonight Show episode will air in September and fans have noted that Justin really only does public appearances when he’s readying for an upcoming release.
