"Big reveal from #TheEternals premiere - Harry Styles has joined the MCU as Eros, brother of Thanos," tweeted Variety's Matt Donnelly on Tuesday morning. The character's big brother Thanos has been played by actor Josh Brolin in both "The Avengers" and "Guardians of the Galaxy" films.

Reps for Styles have not yet responded to requests for comment.
Following on from the events of "Avengers: Endgame", an unexpected tragedy forces the Eternals, ancient aliens who have been living on Earth in secret for thousands of years, out of the shadows to reunite against mankind's most ancient enemy, the Deviants.
Jolie was accompanied by five of her children on the red carpet for the premiere including daughter Zahara, 16, son Maddox, 20, Shiloh, 15, and 13-year-old twins Vivienne and Knox. Zahara was pictured wearing a gown her mother previously wore in 2014 to the Oscars.
