Kevin McHale and Darren Criss perform an eargasmic mash-up of Britney Spears' "Boys" and Justin Bieber's "Boyfriend" on Glee Season 4 Episode 2 titled "Britney 2.0"

Blaine (Darren Criss) and Artie (Kevin McHale) tries to cheer up the depressed Britanny by singing a mash-up of Britney Spears‘ “Boys” and Justin Bieber‘s “Boyfriend.”

Definitely one of the best this season, singing-wise, so far.
