Fact: Harry Styles is now part of the Marvel Cinematic Universe.

It's official, according to reports from the 'Eternals' premiere last night, Harry Styles is introduced into the Marvel Cinematic Universe as Eros; the brother of the supervillain Thanos, during a post-credits scene.

This is Styles' second on-screen role, following 'Dunkirk' (which he co-starred in alongside 'Eternals' actor Barry Keoghan), and precedes Olivia Wilde's 'Don’t Worry Darling' next year.
