"I can't unsee that!" Justin Timberlake and Anna Kendrick react to classic lyrics in Speak Out.

[@blueoceanfloor]

2:47 I can’t be the only one who absolutely geeked out when he sang “I” 🥹🤩 That is one of the coolest I’s I have ever heard in my entire life lol 😳😱

[@MegaGearz]

You aren't we all had high hopes of Justin bringing back some NSYNC 😂

[@TINKERB121]

2:47 when hearing JC Chasez’s voice subconsciously compels you to harmonize.

[@allistar34]

when anna said "that was involuntary"... she wasn't joking haha

[@joeynoname3109]

I guess it's muscle memory.

[@cranesinthesky1240]

the fact that muscle memory means that Justin can just involuntarily harmonise with JC is making me :')

[@prisillasofia3445]

I’ve seen this before and when he hits that “I” I still tear up & my heart soars every.damn.time. It’s involuntary Justin... just let it happen again mannn ya know ya want to!! Reunion👏🏼Ready 💕
