John Krasinski Performs 'N Sync's ''Bye Bye Bye'' on Lip Sync Battle

As if we needed another reason to love John Krasinski.
The former Office star and Emily Blunt's other half took on Anna Kendrick on the latest episode Spike TV's Lip Sync Battle, which aired on Thursday night. the actor told host LL Cool J
"Jimmy Fallon thinks he's a real good friend of Justin Timberlake's, but he ain't this good of a friend" before adding,, "Because I'm doing 'Bye Bye Bye'" Cue Krasinski lip syncing for his life to the 2000 hit while performing spot-on marionette moves—and giving the boybanders a run for their money. No surprise, we can hardly contain our laughter as the 35-year-old star dances across the stage, showing off his best "Bye Bye Bye" wave while wearing a headset microphone in true boyband fashion.
