Her daughter Chelsea is getting married on July 31 in upstate New York, and both parents are, she says, nervous wrecks.
She joked about husband Bill Clinton that "You should assume that if he makes it down the aisle in one piece it's going to be a major accomplishment.
"He's going to be so emotional, as am I," Clinton told NBC's Andrea Mitchell, speaking from Islamabad, Pakistan.
Clinton refused to reveal further details about the wedding. "My lips are sealed. I am under very strict orders not to talk about it," since it is a private matter.
Chelsea, 30, plans to marry investment banker Marc Mezvinsky on July 31 in Rhinebeck, NY.
