Jessica Simpson performed at Lowes Motor Speedway. She wore a Dale Jr. tank top and a sexy pair of black micro shorts. It’s the height of summer and Simpson has the perfect excuse to show off some skin, boobs and legs inclusive, in the hot weather. She was asked about the rumor on having a ring bought from a jewelry store and she laughed it off. She said she couldn’t drag her boyfriend, Tony Romo, into that kind of jewelry store.
