The 38-year-old fashion designer was spotted enjoying a date night with her husband, Eric Johnson, in Los Angeles on Friday night, just four weeks after giving birth. Simpson and Johnson welcomed their third child together, daughter Birdie Mae, on March 19.
The blonde beauty stepped out in a pair of sky-high cheetah print heels, which she paired with a flowy black dress with floral details. Simpson opted for simple makeup, and let her long locks hang over her shoulders in loose waves. The mom of three kept close to Johnson, who was dressed casually in a blue button-up, black jeans and velvet shoes.
Simpson happily joked over her "resurfacing of cheekbones" alongside a glam selfie she posted to Instagram just hours before.
Johnson and Simpson also share two older children -- 6-year-old daughter Maxwell and 5-year-old son Ace. In an interview with ET last October, the Dukes of Hazzard star said her kids were excited to help out with their baby sister.
"They're so excited, because they're only 14 months apart, so they didn't get to experience the excitement of each other," Simpson said. "But when I told them that we're having another baby, I know that they'll remember that for the rest of their lives."
"They are most excited about learning how to do the swaddle. Maxwell, my daughter, is just so happy that it's a girl," she added.
