If Gael Monfils and Elina Svitolina were planning on having kids, they might need to re-think things.
Svitolina took to social media on Saturday to share a brutal video of Roger Federer nailing her fiance Monfils below the belt with a ball.
NOT LIKELY: Coach's brutal snub for Serena Williams
The three were on the practice court ahead of the French Open when they decided to have some fun.
Svitolina appeared eager to task Federer's accuracy with a defenceless Monfils lined up against the back fence.
The idea was for Federer to hit three balls - one to Monfils' left, one to his right and one between his legs.
“I know it’s a big challenge for you but just try to relax your arm, and you can do it,” Svitolina said to Federer.
Unfortunately for Monfils the Swiss legend showed he hasn't lost any of his precision, sending the third ball straight into Monfils' groin.
The Frenchman doubled over in pain as Svitolina and Federer struggled to contain their laughter and shock.
"Don't try this at home," Svitolina said to the camera.
Federer took to Twitter to apologise, writing: “Sorry @Gael_Monfils, I am out of rhythm. We try it again in a few weeks."
Svitolina and Monfils announced their engagement in April, just two months after saying they had taken a break from their relationship.
“YES!!! To the beginning of our forever,” Svitolina wrote, with Monfils adding in his own post 'She said yes' and referring to his fiancee as 'Madame Monfils'.
Federer plays down chances of French Open success
Earlier this week, Federer said he is not playing well enough to have a chance of winning the French Open after the Swiss' preparations for the clay-court grand slam were cut short in Geneva on Tuesday.
The 39-year-old was up 4-2 in the final set against World No.75 Pablo Andujar of Spain, but lost the next four games to lose 6-4 4-6 6-4 in his only tuneup event on clay before the French Open starts on May 30.
It was Federer's first match since his comeback in Doha in March after sitting out over a year due to two knee surgeries.
"I think when you played so little and you know where your level is at, and I think you saw that today, how can I think of winning the French Open?" the 20-times major winner told reporters.
"I'm just realistic that I know I will not win the French and whoever thought I would or could win it is wrong.
"Of course, crazier things might have happened, but I'm not so sure in the last 50 years at the French Open, somebody just rocked up at 40-years-old, being out for a year and a half and just go on to just win everything straight."
Federer said the next few weeks were important for his season.
"Regardless if you play tournaments or not, if you're back on the Tour or you're practising again with top guys that you go through the rhythm ... how it feels to be back on the Tour and this is then how you start taking better decisions," he said.
"So when I walk out of a match like today, and I feel like 'My God, I could play so much better'.
"It feels strange and it's disappointing, but at the same time, this is the process I need to go through and that's why I can't get too down on myself and I need to go back to the drawing board."
