Donald Trump told "Extra" he's vowing to wow when he says "I do" to longtime girlfriend, model Melania Krauss on January 22nd, and it's sure to be the wedding of the decade. "We're going to have a great wedding," Trump insisted. "We're going to have a lot of fun."

The ultra-extravagant event will be held at Maralago, Trump's posh Palm Beach resort in the brand new, 11,000-square-foot ballroom, and Trump told us all about it. "I don't think there's anything like it comparable anywhere in the world, any ballroom ever built in the world," he told us.

And Trump's wedding planner, Preston Bailey, can vouch for The Donald. The famed wedding planner, whose fantasy weddings include Liza Minnelli's last wedding in 2002, told us that while the real estate mogul developed the ballroom, it's Melania who has been doing all the dazzling details of the big event.

"She has a really elegant approach to design," Preston said of Melania.

And while this is Trump's third trip down the isle (he formally married Ivana and Marla), this is Melania's first wedding. And now reports claim that TV executives want to turn the big day into a live TV show. But Trump gave us the real lowdown.

"They want the wedding on live television," Trump admitted. "I think it's unlikely but they are putting a lot of pressure. It's sort of my day and her day more importantly."

Well, whether it's on TV or not, we can guarantee it will be a day that is sure to rival any wedding spectacular in recent memory.
