Sure, having Lady Gaga, Will Smith, U2, Joan Rivers and Kim Kardashian, amongst others, appear on Jimmy Fallon’s debut episode as host of “The Tonight Show” is impressive, but, as any girl under the age of 15 will tell you, it could have used more Harry Styles. It’s not a party until One Direction’s cutest crooner (yeah, I SAID IT) has shown up. No word on where the real Harry was, but Kristen Wiig noticed the oversight and did her pal Jimmy a solid by showing up as a guest on his second episode as Harry Styles. She even sang! Kristen Wiig as Harry Styles may be my favorite Wiig’s impersonation yet.
