Serena, 36, shared a video of herself speaking French to Olympia on Instagram. She can be heard saying "wash your hands" in French as her little girl puts her hands in the dog's water bowl.
Laughing, the tennis star tells Olympia not to use the dog's bowl to wash her hands. She adds, jokingly, "Oh là là!"
"Now I have to give her a bath," Serena captioned the clip, adding the facepalm emoji.
Serena also sounds like she's in better spirits than she was following her emotional loss at Wimbledon. "It was such an amazing tournament for me," she said after the final match. "I was really happy to get this far. It's obviously disappointing, but I can't be disappointed. I have so much to look forward to. I'm literally just getting started."
