Taylor Swift on Thursday testified against former radio DJ David Mueller, whom she has accused of groping her during a 2013 meet-and-greet. Mueller has denied that he assaulted the singer, saying that her false allegations led to the loss of his “dream job” at 98.5 KYGO.

Swift had a lot to say about Mueller’s lawsuit and her countersuit when she took the stand in Denver federal court, and her many responses to Mueller’s attorney, Gabriel McFarland — including “You can ask me a million questions about it and I’m never going to say something different” — are getting reactions from celebrities on social media. Read on to see what Lena Dunham, Nelly Furtado, Hayley Williams, and more stars had to say.
