Ashlee Simpson and Evan Ross are officially married!
Ashlee, 29, and Evan, 26, were married at the Connecticut home of singer Diana Ross -- Evan's mother -- surrounded by close family and friends in a private, outdoor ceremony on Sunday.
Ashlee's sister Jessica served as maid of honor and friend CaCee Cobb was a bridesmaid. According to a rep, it rained 30 minutes before the event, and a rainbow appeared as guests arrived.
After the ceremony, Diana released a statement to ET, saying, "The wedding went perfectly. We had a beautiful rainbow surrounding us...
"Loving family and friends, great music, great speeches from caring friends and joyful children dancing the night away.
"I thank everyone who supported us on the spectacular day and our neighbors who were kind enough to let us have fun.
"We had great friends that traveled from Norway, London, Switzerland and from all over the world.
"Wishing Evan and Ashlee congratulations.
"I want only love , happiness , joy for my son and his bride."

At the reception, Diana sang "Endless Love" to Ashlee and Evan in a very special once-in-a-lifetime moment.
Ashlee and Evan went public with their relationship in July 2013, and things quickly got serious between the two, with Evan calling Ashlee "the One" last November at the Los Angeles premiere of The Hunger Games: Catching Fire.
"Yeah, she's the one," he told The Insider. "It's amazing. I'm so in love and we've got amazing things going on. And we inspire each other. So it's cool."
The two got engaged in January in Hawaii.

This will be the second marriage for Ashlee -- she and her ex, Fall Out Boy's Pete Wentz, divorced in 2011 after three years of marriage.
They share one child together, five-year-old Bronx Mowgli.
Ashlee's dad went on Twitter earlier today to congratulate her and Evan.
Today my little girl gets married.
Congrats Ashlee and Evan http://t.co/tMckRRJdjB— Joe Simpson (@papajoesimpson) August 31, 2014
