In a strange twist, Terry also got Kate Upton to demonstrate the "cat daddy" dance.

Sports Illustrated swimsuit model Kate Upton is in a tiny bikini doing the cat daddy dance in a video online.

The 19-year-old Michigan native shows off her dance moves using Bay area rap trio The Rej3ctz' hit "Cat Daddy."

The incredible bouncing action occurs during a photo shoot with brilliant photographer Terry Richardson.

Global Grind muses:

"In a strange twist, Terry also got Kate to demonstrate the "cat daddy" dance while wearing a very small bikini. Even though she didn't do the trendy dance for very long, Terry hit the instant replay and slow motion on the video and stretched it out for everyone's viewing pleasure."

Indeed.

Amazingly, those breasts mostly stay in that tiny swimsuit top.
