Jessica Simpson's Killer Legs Are on Display in Gym Shorts After a Pre-Wedding Workout—See the Pic!

Mother of two is in the best shape of her life

Jessica Simpson can't help but flaunt her fit bod around town!

The mother of two was spotted running errands in Beverly Hills earlier this morning wearing head-to-toe Lululemon and looking downright fab.

Wearing a pair of running shorts, sneakers and a tight-fitting jacket, Simpson showed off her killer curves and insanely toned legs while leaving her dermatologist's office.

And whether she came from the gym, or was about to head to a workout, Simpson's clearly sticking to her rigorous routine in order to feel her best on her wedding day.

The former Fashion Star mentor is due to tie the knot with fiancé Eric Johnson over the July 4 weekend, and according to our source, is planning a "classic and modern" wedding.

In fact, Simpson's hubby-to-be is letting his leading lady handle all of the finishing touches on their upcoming nuptials.

She is "all hands-on for her wedding and her husband...is sitting back and enjoying letting Jessica make a lot of the decisions for their wedding day. He is a very laid-back guy and just loves seeing Jessica happy, especially on her big day."

It's only a matter of weeks before we hear wedding bells for these two!
