Sports Illustrated cover girl Kate Upton is busting out (her moves) to a new dance, called the Cat Daddy, and Terry Richardson filmed her demonstrating it.
We have no idea what inspired this ... though it's pretty obvious.
Richardson, a noted fashion photographer perhaps best known for his many provocative Lindsay Lohan photos, may have set the bar too high here.
After all, how can you ever top this ... at least if you're a guy?
Kate Upton isn't opposed to showing off her dance moves online, having done the "Dougie" in a similar video back when that was big. Like eight months ago.
