Following the service, Nancy will be laid to rest next to her husband, who died June 5, 2004, on the grounds of the presidential library.

"Ronald and Nancy Reagan were defined by their love," said former Secretary of State James Baker at the service. "They were as close to being one person as it is possible for any two people to be."

Baker credited Nancy for much of Ronald's success as President of the United States.

"She had an instinct for reading people that the president knew he lacked," Baker said. "Nancy was the president's eyes and ears on personnel. She could see who was paddling their own canoe and who was loyal to the president. And she was as tough as a Marine drill sergeant -- as many of us found out when things didn't go well."

Davis agreed with Baker about her parents' fierce loyalty to one another.

"My parents were two halves of a circle," she said. "Nobody truly crossed the boundaries of the exquisite space that was theirs."

Outside the service, Clinton spoke to ET exclusively about her fondest memories of Nancy.

"She was always so gracious and welcoming to me, but I also remember her strength and her resolve following the attempted assassination of her husband," Clinton said. "She really helped to guide our country through that time."

Amid the sadness in the room, son Ronald Prescott reminded the guests of how fun-loving his mother was.

"She would want this to be a party," he said. "This is not a tragedy. This is a celebration."

Nancy died on March 6 from congestive heart failure at her home in Bel-Air, California. She was 94. In lieu of flowers, Nancy has requested that contributions be made to the Ronald Reagan Presidential Library and Foundation.
