10. Tom Cruise & Katie Holmes – $3 Million
Their 2006 wedding at Odescalchi Castle in Italy was as theatrical as one might expect from Tom Cruise. The medieval setting, elaborate fireworks, and Giorgio Armani-designed attire made it feel like a blockbuster event.
Though the marriage didn’t last, the lavish ceremony, complete with a traditional Scientology component and celebrity guests, left a lasting impression in pop culture history.
