Um, Jessica Biel can't possibly be happy about this sexy onscreen hookup!

Justin Timberlake has released the music video for his new single "TKO," and not only does he get dragged around in the dirt behind a truck for a good portion of the video, but he totally sucks face with Elvis' granddaughter (who is wearing nothing but a pair of panties and one of JT's shirts)! Scandalous!

Wonder how Riley snagged this role in the vid?
