Damian McGinty, who played Rory Flanagan on the show’s later seasons, said he was ‘sick’ over the news.

And Vanessa Lengies, who played Sugar Motta, shared her love for Rivera.

When he first heard the news, Iqbal Theba, who played Principal Figgins, tweeted, “Oh God… mercy… please…,” before tweeting that he hoped this was a “big joke.”

Meanwhile on Instagram, Heather Morris, who played Rivera’s love interest on the show, Brittany S. Pierce, posted a story on her page. The post read, “We need your love and light.”
