Paul McCartney and Heather Mills

Year: 2002

Location: Glaslough, Ireland

Est. Cost: $3.6 Million

Beatles legend Paul McCartney and model Heather Mills’ 2002 wedding was a grand yet ultimately regrettable event; if you don’t know, you’ll soon learn why. Held at a private castle in Glaslough, Ireland, the celebration featured a vegetarian menu and high-profile guests, including Ringo Starr.

According to later accounts, Heather designed her own dress and walked down the aisle to Paul’s song “Heather.” A bit on the nose? Perhaps. Despite the lavish setting and joyous occasion, Paul later called the whole affair a “mistake of the decade.” Tabloid reports claim the wedding’s total cost was $3.6 million, reflecting the couple’s initial optimism and grand ambitions.
