As James chatted about his own upcoming project, Jason, who was sitting in the middle, leaned in to him and completely turned his back on Nigella.

Fans were quick to take to Twitter, aka X, to slam the behaviour, with one user, Lady Eileena, writing ‘how bad mannered … turning his back on Nigella, cutting her out of the conversation.’

User Chris noted the ‘awkward body language as Jason Momoa turns his back on Nigella… what’s that all about?’

And as one user put it: ‘Why is Jason Momoa pointedly sitting with his back to Nigella Lawson?’

It comes ahead of the release of Aquaman And The Lsot Kingdom, which sees Jason taking centre stage in his role as the titular superhero alongside Nicole Kidman as Atlanna and Yahya Abdul-Mateen II as Black Manta.

Aquaman 2 follows Black Manta as he unleashes an ancient and malevolent force after failing to defeat Aquaman, who in turn forges an unlikely alliance with his brother Orm, the former king of Atlantis to save the world from destruction.

Aquaman and the Lost Kingdom is set for release on December 22.
