Milly Alcock’s chef boyfriend: inside the Supergirl star’s 2026 romance
Supergirl star Milly Alcock is flying high on screen—and turning up the heat off it—with a romance with a talented chef.
With Supergirl set to hit movie screens, a lot of you have started asking the other question: who is Milly Alcock dating? Short answer: she is in a relationship, and yes, the guy really does cook for a living.
So, who is he?
Milly Alcock is dating Joseph 'Jo' Powell, a professional chef who keeps things pretty low-key online. There is not a ton of personal info out there about him, but professionally, he is all-in on food. Powell runs a creative project called Schoolnights — and if you also see it written as School Nights, that is the same thing — which does pop-ups and restaurant residencies.
School Nights, explained (without the fluff)
On Instagram, Powell goes by @_jopowell. His bio reads: 'Runner of@schoolnightsltd'. School Nights is described as a collective built around food, music, and offline events. Translation: not just a menu, but a whole vibe. His feed is wall-to-wall kitchen life — carefully plated dishes, seasonal menu teases, and those blink-and-you-miss-it flashes from the middle of a busy service.
The latest from his kitchen
Earlier this year, Powell kicked off a new menu and announced it the way chefs do now — with an Instagram caption that doubles as a mission statement:
'APPY NEW YEAR, kicking the year off with a fresh new menu, ofc keeping the classics, so do not fear !'
Why fans care right now
Between House of the Dragon and her upcoming turn as Supergirl, Alcock is everywhere on screen. Off screen, her world currently looks like a mash-up of red carpets and serious kitchen cred. That combo has people on social platforms digging for details — but beyond the fact that she is dating Powell, and he is busy building School Nights with pop-ups and residencies, that is the gist.
