"I'm just supposed to walk her down the aisle and pay the bills," Clinton told Ryan Seacrest on his KIIS-FM radio show Monday morning.
The details of Chelsea's wedding to fiancé Marc Mezvinsky are up to "Chelsea and her mother" Secretary of State Hillary Clinton, said the father of the bride-to-be. "They're having a good time doing it."
But the former president is beaming with joy over the couple's impending marriage. "I must say I am very happy," he said. "My daughter is happy. I like and admire my future son-in-law, so I couldn't be happier about it."
Asked if he expected to shed some tears on his only daughter's wedding day, Clinton said, "Probably. I always thought being her father was my most important job, so it's a big day for me. [It's] the biggest day in her life, probably, and I'm happy."
Chelsea, 29, and Mezvinsky, 31, an investment banker, became engaged last November.
