High Five: 5 facts about Boris Becker you probably didn't know

Boris Becker is rather known as a bon vivant, but the tennis star is also the author of a parenting guide. In "Was Kinder stark macht" (What makes children strong), from 2007, he wrote about his love for the three children he already had at the time. However, the book is more for fans than for worried parents; critics didn't consider the work to be very serious.

Speaking of children, whoever believed the Becker kids would follow in their dad's footsteps are wrong. None of them can play tennis that well. The oldest son, 23-year-old Noah, (pictured) is a DJ and artist, Elias (18) collects likes on Instagram, his daughter Anna (17) is a successful model and his youngest son, Amadeus, hopes to become a policeman some day.

Vanity is an essential step to healthy self-confidence, Boris Becker once said. That's why he takes extra good care of his appearance. This includes not only a collection of expensive fine-tailored suits, but also some serious body hygiene: He claims to take three showers a day. After all, his body is his main resource, he explained.

There are presumably a few little boys born in the 1980s or 90s named Boris after the famous tennis star. One researcher even gave his name to a new species. In 1996, biologist Manfred Parth discovered a species of sea snail and officially named it a few years later "Bufonaria borisbeckeri."

"Boom-boom Boris" was one of Boris Becker's many nicknames, as the tennis wunderkind was renowned for his ferocious serves. A German ice cream company had the name trademarked after his Wimbledon win in 1985. In Germany, the "Bum Bum," which has the shape of a tennis racket and a chewing gum stick, is legendary to this day.
