The smile on Cooper's face says it all!

Monsters star Cooper Koch is officially taken!

Koch, who was nominated at the 2025 Golden Globe Awards for his performance on Netflix's hit series Monsters: The Lyle and Erik Menendez Story, walked the Globes red carpet on Sunday, Jan. 5 with his boyfriend, Stuart McClave, by his side.

As one of the most prominent Hollywood stars of 2024, Koch entered 2025 after having a landmark year marked by his powerful, breakout performance as Erik Menéndez on Netflix's Monsters — earning the 28-year-old actor his first Golden Globe nomination. Koch has historically kept a low profile since his career took off. He doesn't have social media, for instance, and also mostly kept his boyfriend's name under wraps during different interviews.

But it seems like Cooper Koch's perspective on sharing his relationship with the public has changed, as Koch not only brought McClave to attend the Golden Globes with him, but posed for several pictures alongside his boyfriend. So, the question remains: who is Stuart McClave?

Is Cooper Koch married?

No, Cooper Koch is not married to Stuart McClave (or anyone else), as reported by People.

When interviewed on Andy Cohen Live and asked why he wore a wedding ring to the 2024 Emmy Awards on his right finger despite not being married, Koch replied (via Page Six):

"We were getting ready, and I didn't have any jewelry on. And I was with my boyfriend, and we went into my room, and I was looking through my jewelry, and I had this ring that was my grandfather's, and I was like, 'Oh, I should just wear this ring. And then we just put it on my ring finger, and it just kind of became this little, like, I don't know, romantic, protective mechanism."

How long have Cooper Koch and Stuart McClave been dating?

The relationship history between Cooper Koch and Stuart McClave is still unclear per multiple reports in the media. Both of them are also not on social media, which makes the timeline of when they started dating even more unclear.

In December 2024, Koch told GQ Australia — during the publication's Men of the Year event — that his "personal Man of the Year" was "my partner, Stuart McClave."

Koch and McClave were then interviewed by Entertainment Tonight while attending the 2025 Golden Globes on Sunday, Jan. 5, 2025. In that interview, Koch discussed what it's been like having his partner along with him during the Monsters release, press tour, and awards season.

"I mean it's intense! It's overwhelming at times, and so he's just got me so grounded and pulls me down to the earth and holds me when it's a lot and he's been so supportive and sweet and just he's been the best partner I could ever, ever ask for," Koch said, kissing his partner on the cheek.

"It's very easy to do that, [to] be the best partner to Cooper," McClave chimed in. "He's so sweet."
