Let's be clear here — we'd call it a "cat fight" even if the two drivers screaming at each other were men rather than the twin female towers o' power of IndyCar — Danica Patrick and Milka Duno (often pronounced "Milk n' Donut"). Apparently Danica thinks Milka's too slow and has been blocking her with the big rear-end of her car whenever she tries to pass the little French pastry. Yesterday after the morning practice at the Mid-Ohio Sports Car Course, Danica decided to confront Duno. We'll let the Indy Star pick up the story from here:

Patrick went to the Dreyer & Reinbold Racing pit box after the morning practice to complain about her struggles to pass Duno, but Duno did not like Patrick's style. [...]

On a video shot by a friend of Duno's and shown to The Star, Duno told Patrick on several occasions to "go away." When Patrick didn't leave immediately, Duno twice threw a towel in Patrick's direction, prompting Patrick to use foul language before the minute-long incident ended.

All we have to say is Me-yowza! [via Deadspin , IndyCar , Indianapolis Star ]
