And as close as their cars.
Maria Sharapova and Jelena Jankovic's cars were spotted parked next to each other.
The two divas were having their training session at Nick Bollettieri's.
Jola, the mother of a full time student at Nick's who shot this video is doing a heck of a good job!
Hopefully this will inspire other mothers of junior tennis players to come up with more priceless training videos :D
