Sebastian, who plays Bucky Barnes aka The Winter Soldier in the Marvel Cinematic Universe, has been in a relationship with Annabelle, who plays Grace Burgess in Peaky Blinders, since 2022.

They’re believed to have first met in May 2022 at Robert Pattinson’s 36th birthday party in New York, shortly after her split from Chris Pine.

They were snapped in public a few times, but have maintained a mostly private relationship.

Annabelle and Sebastian began appearing in public more often in 2024, attending the Cannes Film Festival and some of Sebastian’s film premieres.

Their red carpet debut came at the 2025 Golden Globes. During his acceptance speech for Best Performance by a Male Actor in a Motion Picture, Musical or Comedy, the actor gushed: ‘Annabelle, I love you’.

News that they were expecting their first child together broke in March. They later confirmed the news when Annabelle debuted her growing baby bump at the Cannes Film Festival.

The Gossip Girl alum added that their relationship ‘is not something either of them discuss’ in public.
