Rihanna showed up an hour after the Met Gala red carpet ended for an all-eyes-on-her pregnancy reveal – but it was hardly the first time she made tardiness a trend. Look back at all her late arrivals at the Met Gala.

Rihanna is no stranger to making a fashion statement at the Met Gala: She made her debut at the event in 2007, when she was just 19 years old, and in the intervening years has donned some of the most unforgettable looks in recent Met Gala fashion history, including that canary yellow Guo Pei gown in 2015.

P erennial Met Gala star Rihanna stole the show ahead of her red carpet arrival at the Metropolitan Museum of Art's annual Costume Institute Benefit on Monday night by revealing she is pregnant with her third child with partner A$AP Rocky.
