A celebration full of co-stars, Shadowhunters reunions, and teary vows—inside Alberto Rosende and Tessa Mossey’s unforgettable Prince Edward Island wedding.
Alberto Rosende may have stepped away from the sirens of Firehouse 51, but this summer, the only sparks flying were for love.
On July 27, the Chicago Fire and Shadowhunters actor married longtime girlfriend and fellow actress Tessa Mossey in a dreamy outdoor ceremony on Canada’s picturesque Prince Edward Island. With ocean waves in the background, a tearful groom, and a guest list packed with familiar faces from both hit TV shows, the couple’s wedding was a weekend to remember—for fans and friends alike.
A Love Story That Began in the Shadow(world)
Alberto Rosende first met Tessa Mossey while filming Shadowhunters, the cult-favorite supernatural series where he played Simon Lewis, the geek-turned-vampire. Tessa joined in later seasons as Heidi, a character whose twisted arc collided with Simon’s in dramatic ways. Off-screen, however, the two actors found something more lasting than any magical storyline: a real-life romance that quietly began around 2019.
Fast forward to 2025, and what began as an on-set connection has become a full-fledged Hollywood love story.
A Wedding Full of Familiar Faces — and Heartfelt Moments
Rosende and Mossey’s nuptials brought together more than just their families—it was also a heartfelt reunion for castmates from Chicago Fire and Shadowhunters. Among the groomsmen was Daniel Kyri, who played Rosende’s on-screen best friend, Darren Ritter. Their real-life friendship, forged on Firehouse 51, was on full display as Kyri stood by Rosende’s side throughout the emotional day.
Also in the wedding party: Jake Lockett (Chicago Fire’s Sam Carver), Dominic Sherwood (Jace from Shadowhunters), and Luke Baines (who portrayed Jonathan Morgenstern). All were captured laughing, dancing, and even shedding a few tears in Instagram stories and candid photos from the celebration.
One standout moment? Alberto was seen wiping tears from his eyes as Tessa walked down the aisle in a vintage lace gown with a delicate veil and string of pearls. Later, she changed into a shimmering blue shift dress with white gloves and a shawl, channeling vintage glamour for the reception.
The Ceremony: Coastal Vibes and Unscripted Joy
Held outdoors with the ocean as a backdrop, the ceremony was intimate yet cinematic—just like a Virgin River season finale but with less heartbreak and more oysters.
The couple’s first dance was to Paul Anka’s classic “Put Your Head on My Shoulder,” capturing the retro romance of the entire event. In a moment that felt lifted from a rom-com, guests later hit the dance floor as Dominic Sherwood led a spirited singalong of “Rock DJ” by Robbie Williams.
And yes, oysters were on the menu—served during a seaside cocktail hour as guests toasted to the newlyweds.
From Chicago Fire to a New Chapter
Rosende’s Chicago Fire exit in the season 12 premiere earlier this year marked the end of a significant chapter. His character, Blake Gallo, debuted in season eight as a brash, big-hearted firefighter whose emotional backstory and on-the-edge heroics made him a fan favorite.
“Gallo has been a big part of the show for a long time,” said showrunner Andrea Newman before the season aired. “His departure made sense with the emotional journey he had last season.” The storyline allowed Gallo to exit on his own terms—something rare in the high-stakes world of Chicago Fire.
Co-star Daniel Kyri also left the series at the end of season 13, along with Jake Lockett, making their presence at Rosende’s wedding a full-circle moment for fans and friends alike.
What’s Next for Alberto and Tessa?
While the couple has yet to reveal where they’re headed next, their shared creativity hints at future collaborations—whether on screen, on stage, or elsewhere. For now, they’re basking in the glow of a celebration that blurred the lines between fiction and reality, surrounded by the people who made their journey all the more meaningful.
As far as Chicago Fire fans are concerned, Gallo may have left the firehouse, but his real-life fairytale proves that happy endings do exist—even offscreen.
