Jessica Simpson and her smokin’ bod are just truckin’ along. 

The 35-year-old stunner took to Instagram late Thursday to show off her tight and toned legs as she held on to the side of a truck.

“Truckin,’” she captioned the sexy professional shot, tagging photographer Kristin Burns, who has worked with Simpson before.

Simpson can clearly still rock her daisy dukes with those gams and just last week, she wished her Dukes of Hazzard co-star Willie Nelson a happy 83rd birthday by sharing a flashback photo of the two from the 2005 set.

"Happy Birthday Uncle Jesse," Simpson captioned a snap of them looking at one another. "You are the best human this lady knows. Are you even human? #willienelsonforpresident."

Simpson also recently celebrated another birthday for her daughter, Maxwell Drew, on May 1.
