Take it to the bridge
The bridge of a track is a contrasting section of the song, it also prepares for the return of the original material section — in this case, the hook. A similair line can also be heard in James Brown’s legendary “Get Up (I Feel Like Being a) Sex Machine”, though Timberlake and Timbalake seem to be less insecure about this. Both songs are pretty much about the same thing by the way.
