Former first lady Nancy Reagan praised her late husband Sunday, laying a wreath on his grave and singing "Happy Birthday" with the Beach Boys as actors, musicians, former advisers and friends paid tribute to Ronald Reagan on the 100th anniversary of his birth.
Nancy Reagan greeted the crowd of about 1,500 invited dignitaries under a tent on the east lawn of the Ronald Reagan Presidential Library on in Simi Valley.
"I know that Ronnie would be thrilled," the 89-year-old said, looking skyward, "and is thrilled, to have all of you share in his 100th birthday. It doesn't seem possible, but that's what it is."
After a crowd including son Ron Reagan and former Vice President Dick Cheney rose to its feet in applause, she shouted "Happy Birthday Ronnie!"
Nancy Reagan has made frequent appearances at the library but rarely speaks.
