However, she was quick to shut down the rumors. Gaga shared a close-up of her bleached eyebrows in a video on TikTok with a cheeky reference to Taylor Swift's song "Down Bad," writing in onscreen text, "Not pregnant -- just down bad cryin at the gym." She also used the moment to encourage fans to register to vote in the upcoming U.S. election. Engagement rumors also surrounded Gaga and Polansky's relationship earlier this year, after she was spotted with what appeared to be a large diamond ring on her left ring finger during an April outing. A rep for the singer did not respond to PEOPLE's request for comment at the time. Lady Gaga in Los Angeles on May 23, 2024.
