Shade alert!

Harry Styles pulled a Mariah Carey on his old One Direction band mate Zayn Malik while performing his monologue as host of NBC's Saturday Night Live. The latter had famously quit the pop group in early 2015. The band, consisting of remaining members Styles, Niall Horan, Louis Tomlinson and Liam Payne, announced an infinite hiatus several months later. All five singers have concentrated on solo music careers in recent years.
