Forget FaceTime and Zoom - the celebrity group chat is where it's at. Whether it's Taylor Swift's squad or the cast of The Avengers, these are the famous text chains every fan wishes they could be a part of. Luckily, Hollywood's biggest stars often give fans a bit of insight at what it's like inside these never-ending conversations with their close pals and costars. Riverdale alum Madelaine Petsch described her cast's group chat as "lit" in 2020, while Peter Facinelli revealed that the Twilight cast's group chat is titled "Family" in 2025 - more than 15 years after the franchise debuted.
