Camila Cabello plus Michael Jackson equals music to our ears — literally. On Monday night, Camila was among the performers who hit the stage during Welcome!, a fundraising concert for the ACLU at the Staples Center in LA. Hitting the stage in a t-shirt that read "Resist," the singer nailed all the right notes as she covered Michael Jackson's hit "Man in the Mirror." After the event, she tweeted a message of gratitude, saying, "Thank you @ACLU and @Zedd for a beautiful night. Love only."
