Catherine Zeta-Jones and Michael Douglas

Catherine Zeta-Jones and Michael Douglas tied the knot two decades ago in 2000. At the time, it was considered to be among the most expensive weddings in Hollywood, costing around $1.5 million. It was held at New York’s Plaza Hotel and had 300 guests in attendance. Aside from its price tag, the wedding became known for its highly exclusive photographs. It was released via an exclusive agreement with OK! magazine for $1.5 million. Unsurprisingly, when Hello! Magazine took some unauthorized pictures, the couple and their lawyers sued them.

The couple’s fashion ensemble during their big day was quite elegant and sleek. Douglas wore a dinner suit with a white ribbon tie and a white flower fastened into his chest. Meanwhile, Zeta-Jones wore a custom, hand-beaded gown made by Christian Lacroix. It was reported that the gown cost around $140,000. This made the gown one of the most expensive celebrity gowns ever.
