The trio joined actresses Aishwarya Rai Bachchan, Katherine Langford, Kat Graham, and Aja Naomi King, and "Game of Thrones" star Nikolaj Coster-Waldau beneath the Eiffel Tower for the French cosmetics brand's latest star-studded fashion show.
Cabello, Heard, and Mirren, who all currently serve as L'Oreal ambassadors, showed off the firm's spring-summer 2022 looks, with "Havana" singer Camila wowing crowds in an ivory gown covered in a pink and green floral pattern and "Aquaman" star Heard hitting the runway in a plunging pale pink jumpsuit.
Meanwhile, Mirren opted for a fitted black rock star suit, covered in silver sequins, while wearing dramatic black eye makeup.
Camila Cabello's Paris Fashion Week appearance came following her performance at the star-studded Global Citizen Live concert. She performed live from Central Park in New York, delivering her singles such as "Havana", "Never Be the Same", and "Don't Go Yet".
