Sabine Lisicki was not trying to emulate the Bryan Bros by giving Caroline Wozniacki a chest bump.
Apparently, the girls who dressed like twins, were walking towards their seats during the changover.
The thing was, Lisicki didn't notice Wozniacki, or vice versa. And so they bumped into each other!
Check out Wozniacki's reaction... she looked pretty pissed and had a quick word with the umpire thinking that it was intentional and rude.
