The three richest couples in world rugby

Rugby has produced some of the sporting world's most famous athletes, but for a few, on-field success has also led to immense wealth off the field.

From high-profile marriages to lucrative endorsement deals and television appearances, these rugby stars have built financial empires.

Here's a look at three couples who combined their sporting heritage with fame and fortune and amassed millions in the process.

Mike and Zara Tindall – £20 million

Mike Tindall is known not only for his rugby skills but also for his royal connections. As the husband of Zara Phillips, Queen Elizabeth II's granddaughter, Tindall has become a prominent figure in the British media.

Tindall, nicknamed “The Fridge” because of his imposing stature, was a star on the rugby field and broke his nose at least eight times during his career. Since retiring from the sport, he has made a name for himself in the entertainment world, appearing on popular reality shows such as I'm a celebrity… Get me out of here, Bear Grylls: Mission Survival, The jump, Shark cage, Celebrity Poker ClubAnd All Star Poker Challenge.

Despite his success in sports and entertainment, Tindall's fortune was largely bolstered by his royal connections. According to British media, his net worth is estimated at £20 million.
