Here comes the billionaire and his bride. Donald Trump's spectacular Palm Beach wedding attracted a parade of his powerful and famous friends this weekend, including Rudy Giuliani, Heidi Klum, Katie Couric, Barbara Walters, Tony Bennett, Billy Joel and our very own Dayna Devon.

Oprah Winfrey couldn't make the big day, but her right-hand woman, Gayle King, attended. So did boxing promoter Don King, Paris Hilton's mom, Kathy and "American Idol" judge Simon Cowell, who told us what he thought was the best part of the wedding: "The 'I do.' It was the best 'I do' I've ever heard."

Former President Bill Clinton missed the ceremony, but made the reception, while Senator Hillary Rodham Clinton sat in the front pew of the church with Lakers star Shaquille O'Neal, who scored that seat because of his long legs.

Dayna told us about the ceremony, revealing, "They kissed about four times. They didn't stop kissing."

"It was very nice. It was very touching," Billy Joel added. "It was just a culmination of the vows and the whole place stood up and cheered, and I thought that was pretty cool." And Joel's new bride, Kate, added, "I thought when they kissed and they looked so happy, I got a little misty-eyed."

And although Trump's bride, Melania's dress is said to have weighed 50 pounds, Dayna assured us, "I think she was floating. Her feet never touched the ground."

After the ceremony, dozens of locals raided the church and stole the flowers, one even joking about selling them on eBay. But hype aside, the wedding ended with happiness and warm wishes from Billy Joel, who hopes Donald Trump's third marriage, will be as great as his own: "You know what? This is my third, so I think three's good luck."

After the ceremony, the guests went to Trump's Mar-a-Lago resort for the reception, and the next morning, "Extra's" Tanika Ray met up with Donald's best man, Donald Jr., for a post-party brunch and a little insider info about the big night.

"I am a little tired," Donald Jr., admitted. "I got to bed at three, up at six. It's the Trump schedule, you can't sleep in."

Donald Jr. gave us his take on the big night: "It was a great vibe. It was amazing. It was a who's who of finance, entertainment and everything. When I got up to give the best man speech, I look around and there are 500 of the world's biggest killers. I'm looking at Barbara Walters. I'm looking at Matt Lauer. After 27 years of putting up with my father, he's a great guy, this is my venue for a little bit of revenge."

As for Trump the dancer, Donald Jr. told us, "I was surprised, he pulled out some moves; it went well."

But the topper had to be Billy Joel's serenade for the newlyweds.

So how will the world's most watched just-marrieds spend their honeymoon? "I think he'll take the week off and enjoy himself down here. He is not a kind of hangout-on-the-beach kind of guy."

Well, whatever you do to celebrate your union, we say congratulations, Donald and Melania!
