Love can be a total knockout, but not always in a good way, as Justin Timberlake discovers in the official video for 'TKO.'

The spark between JT and his partner, played by actress and model Riley Keough, has truly been lost until passions flare during an argument and the couple indulge in a quickie on the kitchen counter.

That proves to be a bad move on Justin's part as he literally gets knocked out by Riley, and later tied to a pickup truck driving through the desert which, as cinema has taught us, is never a good thing.

Produced by Timbaland, 'TKO' sits on Timberlake's Billboard-topping 'The 20/20 Experience -- 2 of 2' -- his second No. 1 album of the year -- which is out now on iTunes.
