Chelsea Clinton is going to be a happy bride, especially since her dad, former President Bill Clinton, has kept his wedding promise to lose 20 pounds ahead of her big day.

Bill, 63, revealed that Chelsea -- who herself has lost over 25 pounds -- had asked him to slim down so he can "look good" walking her down the aisle when she weds banker Marc Mezvinsky on July 31, 2010.

Chelsea had asked Bill to lose 15 pounds, but he told reporters Saturday he lost 20 pounds by cutting back on desserts and junk food.

"He looked trim. He lost the weight Chelsea asked him to lose," said Albany native Julie Davis, who ran into Bill at an eatery in upstate New York on July 30.

"I had just sat down for lunch and was ordering iced tea when I heard someone screaming, 'It's him, it's him!" Davis, 35, recounted. She continued: "I said to him, 'Gee, this is a pleasant surprise' and 'Congratulations.' He said, 'Thank you.'"

In February, Clinton underwent heart surgery to open a blocked artery in his heart. Clinton previously had a quadruple bypass operation in 2004.  

'CHELSEA IS ALWAYS BEAUTIFUL TO ME'

Meanwhile, the sleepy town of Rhinebeck, N.Y., is aflutter with excitement over Chelsea's lavish wedding. Over 500 VIP guests, including politicians and other celebrities are expected to attend the wedding of Bill and his wife Hillary's (the current Secretary of State) only child.

Chelsea, 30, has been spotted hitting the gym every day this week to look good on her special day. Bill couldn't be prouder.

"When a reporter called out, "Is your daughter going to look beautiful?" He immediately replied, "She looks beautiful every day to me."

Chelsea's $3 million wedding will take place July 31, 2010 at the former estate of John Jacob Astor IV in Rhinebeck, N.Y. The bride will wear a custom-made Vera Wang wedding dress. [see more wedding pictures here]
