#16: Garth Brooks & Sandy Mahl
Relationship Duration: 15 years
Est. Divorce Cost: ~$125 million
Garth Brooks’s split from Sandy Mahl was monumental in the world of country music — not just emotionally, but financially. At the time, Brooks was the best-selling solo artist in U.S. history, and much of his fortune had been earned during their marriage. Without a prenuptial agreement, the settlement reflected decades of shared effort, as Mahl had supported him through his early career.

Their marriage ended quietly but painfully. Brooks has said fame and time apart were major factors — endless tours, media attention, and his obsession with music left little room for home life. Despite the staggering cost, the two have maintained mutual respect, co-parenting their daughters peacefully ever since.
