The younger sister of Jessica Simpson walked down the aisle at a ceremony held in Connecticut, USA on Saturday, 30 August.
Jessica was matron of honour. Ashlee's wedding came a month after she herself tied the knot with long-time boyfriend Eric Johnson, the father of her children Maxwell and Ace.
Singer-actress Ashlee became engaged to actor Evan, the son of legendary singer Diana Ross, in January. He popped the question while they were on holiday in Hawaii.
It's believed their wedding ceremony took place in the gardens of Diana's home in Connecticut. According to reports, Diana was heavily involved in planning the wedding and even performed at the ceremony.
Evan previously said: "She's involved in every piece of our wedding and engagement party. She's involved in all levels of my life. She's one of the most incredible mothers ever."
Ashlee, 29, and Evan, 25, threw a lavish engagement party in March, inviting friends and family to celebrate with them in a Great Gatsy-themed bash in Los Angeles.
This is Ashlee's second wedding. She was previously married to Fall Out musician Pete Wentz, the father of her five-year-old son Bronx.
Evan will appear in the next Hunger Games movie as Messalla.
