Catherine Zeta-Jones & Michael Douglas – Estimated $1.5 Million

Actress Catherine Zeta-Jones is the second wife of Michael Douglas, and it looks like he was willing to go big or go home for his second try at walking down the aisle. He never told her the exact cost of their big day, but sources estimate it to be around $1.5-2 million.

She wore a gorgeous $140K-worth gown by Christina Lacroix, and the cherry on top was her diamond tiara worth $300K. Both Zeta-Jones and Douglas are still active actors. She most recently starred in prodigal Son, while he will return for the Ant-Man and the Wasp: Quantumania movie in 2023.
