Eugenie Bouchard and Grigor Dimitrov are two of the youngest players in their respective leagues' Top 25. With the fame comes the bizarre appearances - the latest playing one another on a floating course off the coast of Acapulco two days ago.
The pair had plenty of fun, including leaping into the ocean after a few points were played when both agreed it was way too hot to be playing tennis.
The 22-year-old Dimitrov, rather well-known for dating Maria Sharapova, is ranked 22nd in the world.
The 20-year-old Bouchard rose to No. 19 in the world after reaching the Australian Open semifinals last month.
