The two looked loved-up as they posed for photographers on Sunday, attending the Miu Miu photocall alongside a string of other A-listers. Boynton looked angelic in a white gown with puffed sleeves, whilst Malek opted for a a laidback look in a khaki shirt.
That evening, the couple attended the Miu Miu Women's Tales dinner, which saw the Egyptian-American actor change into a tux.
The Hollywood stars met on the set of Bohemian Rhapsody, last year's Queen biopic, which saw them playing an on-screen couple. They confirmed they were dating IRL at the Palm Springs International Film Festival back in January, when the Mr Robot actor paid an adorable tribute to Boynton in his Breakthrough Performance Award acceptance speech.
Malek, who picked up an Oscar for his portrayal of Queen frontman Freddie Mercury in Bohemian Rhapsody, will be playing a villain in the upcoming Bond 25 film, No Time To Die.
