Jessica Simpson puckered up her lips and showed off her makeup-free face via Twitter on Sunday.

The star posted a new photo of herself right before dinner with the caption, "Aquaphor from the diaper bag...And a filter ;) Date night!"

In the black-and-white picture, Simpson wasn't wearing an ounce of powder while out with her fiancé Eric Johnson.

This isn't the first time Simpson has flaunted her no makeup look. In 2010, she even covered Marie Claire without getting glammed up.

"I don't have anything to prove anymore. What other people think of me is not my business," she told the magazine.

While the 33-year-old mother of two has no problem with her natural look, she's spoken openly about her insecurities with her weight.

"My pregnancies (especially my first with Maxwell) were well documented and my struggles with my weight and body image have played out in front of the world," she told Parents.com in October. As hard as that has been, the hardest part is to realize that with all the hurtful and harsh criticism from others, I have been the hardest on myself."
