With all the excitement mounting around Chelsea Clinton's upcoming wedding this weekend (July 31) to Marc Mevinsky, no one is more excited than her proud papa, Bill. Some say he's maybe a little too excited.

"What daddy wouldn't be on cloud nine about his only daughter's upcoming wedding," a Clinton family friend tells me. "The only problem is that when your father is ex-President Bill, a man with a healthy ego, everything starts to become about him."

Sources tell me Chelsea has been gently reminding her larger-than-life father that she wants the day to be on the low-key side, surrounded by her family and dear friends, rather than a huge event filled with Hollywood celebrities and people she hardly knows.
