Nearly 10 years -- and two kids -- after donning her signature teensy jean shorts in 2005's "Dukes of Hazzard" flick, Jessica Simpson is ready to rock the Daisy Dukes again. And she did just that over the weekend, showing off her sculpted gams in a pair of short-shorts as she stopped by 10 Speed Coffee in Malibu, Calif., for a cup of joe. Since kicking off her post-baby fitness program -- and tenure as a Weight Watchers spokesperson -- Simpson has likely trimmed 60 to 70 pounds off her figure, nutrition expert Marco Borges tells E! News. In addition to walking about four miles a day and chasing after her son, Ace, and daughter, Maxwell, Simpson recently told USA Today that her exercise regime has focused on 45 minutes of resistance training, lunges and squats mixed with "cardio bursts" four days a week.
