Heidi Montag Gets Nascar Naughty

Gentlemen, Start Your Engines!

Heidi Montag and Spencer Pratt show some affection on the track at the Nascar Pepsi 500 race in Fortana, Calif. on Sunday. Per usual, there was plenty of kissing and cuddling for cameras!

The Hills stars were treated to a VIP backstage tour, met with some of the drivers and Heidi was given the privilege of waving the green flag to get the race underway!
