Ashlee Simpson's new mother-in-law, music icon Diana Ross, is gushing about this past weekend’s wedding between her son, Evan Ross, and Simpson.

Ross, who both officiated the wedding and performed at the reception, told Us Weekly everything went “perfectly.”

Simpson’s older sister, Jessica Simpson, was the matron of honor at the wedding while their father, Joe Simpson, walked the bride down the aisle along with her son Bronx, 5.

"We had a beautiful rainbow surrounding us, loving family and friends, great music, and great speeches from loving and caring friends, and joyful children dancing the night away,” said Ross.

She also said they had guests travel from “Norway, London, Switzerland, and from all over the world” to celebrate the couple.

This is Simpson’s second marriage; she was previously married to Fall Out Boy rocker Pete Wentz, and the first for Ross.

"I want only love, happiness, and joy for my son and his bride,” said Ross, who sang “Endless Love” at the wedding.
