Serena Williams is one of the greatest tennis players to ever play the game, but she made headlines for a non-tennis related story on Friday.

The winner of 23 Glam Slam titles and her fiancé Alexis Ohanian welcomed their first child to the world on Friday and the couple received plenty of lovely messages online.
 

One of the people who reached out to the couple on Twitter after the news was announced was Williams’ coach Patrick Mouratoglou.
 

However, that wasn’t the only message Mouratoglou sent to the couple as he was quick to remind Williams that it’s time to get back to work now that the baby has finally arrived.
 

He’s most likely kidding around and having some fun at his client’s expense, but he also might be dead serious considering he does train the GOAT.
