"I am officially an MOTB: a mother of the bride," Clinton said Friday in an interview with CNN's John Roberts. "And I am very excited about it"
Clinton's daughter, Chelsea, is engaged to marry Marc Mezvinsky, the son of former congressmen Marjorie Margolies-Mezvinsky of Pennsylvania and Ed Mezvinsky of Iowa.
"For me, [it's] particularly an extraordinary moment to see how happy my daughter is and to have a wonderful man that will become my son-in-law. But it's daunting to try and plan a wedding."

Clinton, who has been criss-crossing the globe since becoming Secretary of State, said she recently received an encouraging call from former Secretary of State Madeline Albright.
"Madeline Albright called me the other night and said, 'Well, when I was Secretary of State and had not a minute to myself, I had to plan a wedding, so if you need any advice, just call me,'" Clinton told Roberts in an interview in Brussels, where she is trying to rally European support for President Obama's new strategy in Afghanistan. "And I said, "I'll be calling."
Clinton said the size of the wedding has not been determined, but noted it would be private.
