Girls just wanna have fun, and Pharrells just wanna hate on girls who wanna have fun. 

The “Happy” artist and winner of last night’s Best Pop Vocal performance cast some serious side eye at America’s sweetheart, Taylor Swift, as the latter jammed out to the likes of Annie Lennox and Madonna.

For what it’s worth, Swift appears to be having too much fun to notice.

Pharrell’s age doesn’t show often –in fact, he’s rumored to be immortal— but he’s looking a little cranky here. Keep dancing, Swiftie.
