Elvis Presley and Dale Earnhardt Sr. are getting hitched. The King and Earnhardt are being paired on a race car that will be unveiled this week at the Las Vegas Motor Speedway. The car, bearing Elvis' image on the hood and Earnhardt's legendary No. 3 on the sides, will be on display at the track throughout NASCAR weekend, one of the biggest annual events in Vegas. Earnhardt, who died during a race in 2001, was instrumental in adding Sin City to the circuit in 1996.
