Don't mess with Texas – or Jessica Simpson.

In the new music video for his song "You Don't Think I'm Funny Anymore" (click here to watch the clip), country legend Willie Nelson bets pals Owen Wilson and Woody Harrelson that the little lady can beat them in the Bad Boy Lawn Mower Race, held in Luck, Texas.

The wager? Ten thousand big ones.

Owen – who made the video while recovering after his hospitalization – and Woody both take the bet, and Simpson took to her mower (a pink one).

And off they all went, along with the other drivers. At one point in the competition, Simpson stops to do her nails. In another, a bearded guy in drag starts to chase after Wilson – who appears to enjoy the attention.
