Milly Alcock is about to hit the big screen again as Clark Kent’s equally heroic cousin, Kara Zor-El, in Supergirl. But you might not know that she’s got a Superman of her own in real life. Enter: Joseph “Jo” Powell, her boyfriend of a little more than a year, who happens to be a chef who loves a cheeky vacay and Instagram photo dump.

The pair has been romantically linked since last year and even made a rare red carpet appearance at the BAFTAs back in February, and honestly? They might be front and center on my romance moodboard. Here’s everything you need to know about Milly Alcock and Jo Powell’s relationship timeline.

Milly may keep things low-key when it comes to her personal life, but she and Jo first sparked dating rumors with his first of many appearances on her Instagram feed. In a since-deleted post shared on June 11, she dropped a pic of their shoes (in which Jo was tagged!) and another of him enjoying a meal and smiling.

In a separate post, Jo shared a mirror selfie with Milly from a trip they took to Lisbon. Cute!

Oh, and they also appeared to attend Glastonbury together, since they pulled up to a pre-fest lunch with Barbour in Bath, England.

Here comes the hard launch! Milly posted another photo dump featuring a ton of pics she took of Jo on film, with the perfect caption: “Mastering the art of hanging out. Ft @_jopowell.” I could literally feel his aura radiating through the screen.

By the end of the month, the pair made their red carpet debut at the Venice Film Festival, where they posed at the Miu Miu Women’s Tales event.

At the end of the year, Jo and Milly each shared a post featuring a black-and-white photo strip where they shared a kiss.

Per Elle, Milly posted a since-deleted photo dump celebrating the year, writing, “2025! 🫨🤭🥹 I know this is lame that I’m doing this but i don’t give a fuck this year has been beyond magical. Thank u to all my friends who made it so special!!! I LOVE U ALL SO MUCH.”

The post included a pic of Jo wearing a T-shirt that read “I ❤️ my girlfriend.” Truer words!!

Milly and Jo had an awards season moment when they walked the red carpet of the 2026 BAFTAs together in London. Based on their chic suiting, something tells me there’s no swag gap in this relationship.

That’s all for now! At least, until Jo potentially makes an appearance with Milly at any point during the Supergirl press tour.
