Chelsea Clinton is pressing dad Bill Clinton to shape up and lose weight for her wedding.

"She doesn't think I'm in shape to handle it," Clinton said. "You know, she told me the other day, she said, 'Dad, the only thing you gotta do is walk me down the aisle, and you need to look good.' "

Apparently Chelsea recommended he lose about 15 pounds and Clinton says he's halfway there.

Clinton added that when he asked her to specify how much trimming down she felt he needed to do, she said, "Oh, about 15 pounds," an effort he said he's "halfway home" toward accomplishing.

Doctors say Clinton has done really well since getting a  cardio-bypass surgery in 2004.

"He really toed the line in terms of diet and exercise," said Dr. Allan Schwartz, the chief cardiologist at New York-Presbyterian Hospital. "He really followed the program."
