Kat McNamara marked World Laughter Day on May 4, 2026 with a career-spanning photo gallery on Instagram. The post pulled together faces from nearly every chapter of her professional life. Her caption read: “Happy #WorldLaughterDay! 😆 Life has its ups and downs but this really is the best medicine! Too many memories to fit in one post, but here’s a few to brighten your day. So grateful for all these moments and more giggling at everything and laughing til it hurts with people I love. 💛”
The gallery collected more than 11,000 likes by Sunday afternoon.
McNamara, best known for playing Clary Fray on Freeform’s Shadowhunters, tagged former co-stars Alberto Rosende, Dom Sherwood, and Matthew Daddario. Shadowhunters ran for three seasons and built a devoted fandom around its cast chemistry. Those three names surfacing in a casual, laughter-themed photo dump says something about how much that bond still matters to her.
The gallery didn’t stop there. McNamara also tagged Matt Barr and Justin Cortez from Walker Independence. That CW prequel came after her Freeform years. Will Tudor, another Walker Independence collaborator, appeared in the tag list too. The photos seem to span years of work rather than any single moment in time. The post reads more like a gratitude journal than a highlight reel. That personal framing, choosing a quirky wellness holiday to honor the people in her life, says something real about how she values the relationships she builds on set.
A few tags added a looser, more playful energy. Ken Jeong and Jimmy O. Yang both showed up in the mentions. Neither is a co-star from her main TV projects. McNamara has clearly built friendships well outside the Shadowhunters or Walker Independence circles. Teen Vogue also got a tag, pointing to a press appearance or creative collaboration somewhere in the timeline.
The IndyCar and Indianapolis Motor Speedway tags raised some eyebrows. McNamara has made appearances tied to IndyCar events before. Her enthusiasm for motorsport has come up in various interviews. Tagging the speedway alongside all her acting colleagues feels personal rather than strategic. It reads like she genuinely counts those days at the track among her favorite memories.
One tag drew the most curiosity: @hallmarkchannel. McNamara has no publicly announced Hallmark project on her upcoming credits. She’s attached to The Queen’s Jewels. That film also got a tag, alongside co-stars George Akram and Natalia Martinez. But the Hallmark mention sits outside that project’s world entirely. It could signal a holiday movie in the works, or a collaboration still under wraps. For now, it’s an open question.
The range of people McNamara chose to honor here is genuinely striking. The list runs from major television networks to an IndyCar circuit, from a Constantin Film production to what might be a Hallmark Channel deal in the making. McNamara has moved steadily from genre television to broader mainstream work. This gallery quietly maps the whole journey.
Her caption didn’t read like a promotional moment dressed up in holiday clothing. She wrote about “laughing til it hurts with people I love,” and the tag list backed that up. These weren’t just industry contacts. They looked like friends.
World Laughter Day is observed annually on the first Sunday of May. It was created in 1998 as part of the World Laughter Yoga movement. McNamara’s take on it skipped the wellness messaging and went straight to the people. That instinct says something real about how she thinks about her work. The craft brings you to the set, but the friendships are what you carry forward.
