BUSTED: Stewart's Good Luck Booty Grab!

Racers have always been a superstitious lot. But defending NASCAR Sprint Cup Series champion Tony Stewart has taken the concept of “good luck charms” to a whole new level. 

Delana Harvick – wife of fellow driver Kevin Harvick --  and Sirius XM NASCAR Radio host Angie Skinner have both been targets of Stewart’s devotion to ritual in recent seasons; victims of a pre-race “booty grab” that Stewart insists was the impetus behind his improbable 2011 championship run. 

Harvick recently returned to the track for the first time since giving birth to son Keelan on July 8, and the groping resumed almost immediately. ESPN’s caught Sunday’s latest installment, as part of the network’s GEICO 400 pre-race coverage.  

For the record, Stewart has been known to “goose” Kevin Harvick, as well, when the opportunity presents itself.
