After walking away from Chicago Fire, Alberto Rosende has officially stepped into a new chapter—one not scripted, but straight from the heart. On July 27, 2025, the beloved actor who portrayed Blake Gallo tied the knot with his longtime partner and fellow Shadowhunters alum Tessa Mossey, in an outdoor ceremony as stunning as it was sentimental. But this wasn’t just any celebrity wedding—it became a reunion of two fan-favorite TV worlds, full of surprise cameos, heartfelt tears, and behind-the-scenes magic.

The wedding took place on the picturesque shores of Prince Edward Island, Canada, where friends and family gathered to celebrate a love story years in the making. Alberto and Tessa first met on the set of Shadowhunters, where he played the geek-turned-vampire Simon Lewis, and she portrayed Heidi, a dark and tragic character with her own vampiric arc. Offscreen, their connection bloomed into something real—and now, permanent.

The ceremony was a breathtaking lakeside affair. Tessa floated down the aisle in a vintage lace gown, complete with a dramatic train and a delicate string of pearls. Clutched in her hands was a bouquet of white blooms laced with greenery. Alberto, overcome with emotion, was visibly wiping away tears as he waited at the altar. Their vows, reportedly written by the couple themselves, brought many in the crowd to tears—including some very familiar faces.

Joining the celebration were Alberto’s Chicago Fire co-stars, including Daniel Kyri (Darren Ritter) and Jake Lockett (Sam Carver), both of whom stood beside him as groomsmen. Their bond, forged in the firehouse and cemented in real life, brought fans joy when shared on social media. Kyri and Rosende, in particular, have often described their on-screen bromance as a mirror of their genuine friendship—and this weekend, it was on full display.

But that wasn’t all. Dominic Sherwood, who starred with Alberto in Shadowhunters as Jace Wayland, also donned a groomsman’s tux. He wasn’t just part of the wedding—he lit up the reception, ditching his jacket and jumping into a wild dance to Robbie Williams’ “Rock DJ” while encouraging guests to join him on the floor. Luke Baines (who played Jonathan Morgenstern on Shadowhunters) was also spotted among the guests, sitting alongside Chicago Fire’s Miranda Rae Mayo (Stella Kidd).

It wasn’t just a union of hearts—it was a rare cross-universe reunion that had fans from both shows buzzing online. One fan on X (formerly Twitter) wrote: “This wedding just gave me everything—Gallo, Ritter, Jace, and Heidi all in one event? My multiverse just exploded.”

As the day turned into night, Tessa changed into a dazzling blue shift dress covered in diamantés, paired with white gloves and a shawl, giving old Hollywood vibes with a fresh, modern twist. The couple shared their first dance to Paul Anka’s “Put Your Head on My Shoulder,” swaying under string lights in a moment that felt suspended in time.

Oysters were served. Laughter echoed across the lawn. And though it was a wedding, it also felt like a farewell of sorts. Alberto’s departure from Chicago Fire in Season 12 had left a hole in the series, one still felt by fans. His final episode was an emotional one, and showrunner Andrea Newman noted how difficult it was to say goodbye to a character that had become a staple since 2019.

“Gallo had a big arc. His story came full circle, and the timing felt right,” she said before the Season 13 premiere. Still, as seen at this wedding, the emotional bonds forged in Firehouse 51 continue well beyond the NBC screen.

Coincidentally, Daniel Kyri and Jake Lockett also exited the show in Season 13, which wrapped this past May. Their presence at Alberto’s wedding—cheering, hugging, and reminiscing—offered fans a rare, unscripted look at the real camaraderie among the cast.

As the night wore on and the music played, friends took to social media to share their joy. Behind-the-scenes videos showed Alberto and Tessa performing a hilarious improv dance routine, a reminder that even as life changes, some things—like laughter and love—remain constant.

Tessa and Alberto’s journey may have started in a world of demons and vampire clans, but it’s now grounded in something far more human: commitment, family, and joy. Their wedding was a collision of fantasy and reality, of fiction and truth—a celebration of everything they’ve built on-screen and off.

And though Alberto may have left Chicago Fire, it’s clear he still carries its spirit with him.
