16. Donald and Melania Trump - 2005
Estimated Cost: $1 million
Okay, so $1 million doesn't seem that crazy compared to some of these weddings, but their big day would've been a lot more expensive had they not had the reception at Trump's Mar-a-Lago estate. Their 2005 wedding featured 400 guests (at $275 a plate) and a 36-piece orchestra. Tony Bennett and Billy Joel also performed.
