There's speculation that Lena Dunham and Jack Antonoff split because he got involved with Lorde!
A friend told Us Weekly how for months Lena and Jack were emotionally distant. “They took forever to break up. By the end, Lena knew he was probably dating someone else.” Very likely the other woman was Lorde.
Last year, they spent a lot of time in the recording studio. Their timelines reveal an intense relationship that possibly became intimate. On his birthday, Lorde Instagrammed ending with their initials, “Ours is a relationship that will be special and vital for a long time. JA + EYO forever and always.”
Lena dropped a significant clue that she suspects mischief between Lorde and her ex-boyfriend. She’s deleted from social media every reference to Lorde working with Jack Antonoff. He wrote all the music and produced her Melodrama album.
