Several of Michelle’s other Gossip Girl costars, including Blake Lively, Ed Westwick, and Chace Crawford, have also shared heartfelt statements since her passing. Shortly after the devastating news came out, Blake shared a throwback photo of her and Michelle on the set of GG and wrote, “She was electricity.

Blake gushed more about Michelle, calling her a “kind person, through and through,” “fiercely loyal,” and “distinctly herself.” She reflected, “Time passes. You take for granted that you get the chance to see an old friend. To paraphrase, the real tragedies in life are the ones that blindside you on an idle Tuesday.”

Chace remembered Michelle with an Instagram tribute featuring photos of him and the Harriet the Spy actress over the years. “She was a force of nature and just so so unapologetically funny and magnetic,” he wrote in his caption. “Remembering those years with a big smile. Just a terrible loss. Love you ❤️.” In a statement to People, Ed shared, “It’s been a long time since I’ve seen Michelle but I remember a talented, sharp, funny and warm soul. He added that he was thinking of her and her family.
