But Hailee Steinfeld looked perfectly unbothered as she hit Universal’s after party hosted by Soho House at The Ned.
The actress, 23, certainly showed her ex what he was missing as she wore her stunning red carpet navy blue floor-length dress to the bash.

She wore her brunette hair in a sleek straight centre-parting and finished off her glamorous outfit with a polished make-up look.
Throughout the night, guests drank a steady stream of cocktails supplied by Patrón Tequila, including twists on classics including an Añejo Old Fashioned and a Picante de la Casa.
Hailee and Niall were believed to have started dating in November 2017, although neither of the pair ever publicly confirmed the romance.
Their romance was said to have come to an end the following December, with Hailee putting an end to the relationship because of her ‘insanely busy’ schedule.

Fans believed her recent single Wrong Direction is about their failed relationship.
The lyrics include: ‘I don’t hate you / No, I couldn’t if I wanted to / I just hate all the hurt that you put me through / And that I blame myself for letting you.’
But Horan apparently wasn’t fazed, as a source told Metro: ‘Niall is not losing any sleep over Hailee’s upcoming single.
‘He knows the name of the game when it comes to music and these type of songs will happen from time to time, he’ll likely do it in the future himself.’
Case of the ex: Hailee risked an awkward run-in with her ex-boyfriend Niall Horan at the Brit Awards
