When you’re iconic enough to go by a mononym, people might not know your last name — including your costar. 😅 While playing a guessing game on #TheOdyssey press tour, Matt Damon gave clues steering Zendaya toward identifying her #Euphoria costar Colman Domingo. "Do we share a name?" the actress — born Zendaya Maree Stoermer Coleman — asked before realizing, "You might not know my last name." Damon appeared slightly unsure as he struggled to answer the question. "Uhhhh…" he muttered, while someone off camera confirmed, leading Zendaya to guess correctly. 📷 Melinda Sue Gordon/Universal Studios; Jeff Kravitz/FilmMagic 🎥 mtvuk #zendaya #mattdamon #colmandomingo
