British tennis player Harriet Dart has apologized after asking the chair umpire to tell her opponent to put on deodorant because she “smells really bad.”

Dart lost 6-0, 6-3 to French player Lois Boisson in the first round of the clay-court Rouen Open on Tuesday, and was picked up by a microphone during a changeover telling the umpire: “Can you tell her (Boisson) to wear deodorant? … Because she smells really bad.”

After the footage spread on social media, Dart posted an apology on Instagram and said “it was a heat-of-the-moment comment that I truly regret.”

“That’s not how I want to carry myself, and I take full responsibility,” she wrote. “I have a lot of respect for Lois and how she competed today. I’ll learn from this and move forward.”

She posted a photo on Instagram of her on court with a Dove deodorant edited into the frame above her hand, tagging the company and writing that they “apparently need a collab.”
