Hollywood is buzzing after explosive photos and insider testimony suggest Chicago Fire’s Taylor Kinney and Chicago PD’s Marina Squerciati have been in a steamy secret relationship for months.
Sources claim the two actors grew extremely close during intense crossover episodes last season. What started as on-screen chemistry quickly turned into real-life sparks. “They tried to hide it at first,” a production insider revealed. “But everyone on set could feel the energy between them. Late-night script reads turned into private dinners, and it escalated from there.”

The alleged couple has been spotted multiple times in discreet Chicago locations, including a romantic weekend getaway last month. Kinney, who has kept his personal life extremely private since his split with Lady Gaga, reportedly told close friends that Marina “understands him like no one else.”
Squerciati, who plays Burgess, has also been glowing lately, according to co-stars. “She’s happier than we’ve seen her in years,” one PD crew member said. “The chemistry between her and Taylor is off the charts, both on and off camera.”
This bombshell comes amid swirling rumors of tension with other cast members who feel the secret romance is affecting on-set dynamics. Some insiders even claim showrunners are considering writing their characters into a surprise crossover romance to capitalize on the real-life buzz.
Social media is completely divided. Fans are shipping “Tayrina” hard, while others worry it could ruin the professional environment of the interconnected franchise. Will Dick Wolf lean into this romance or try to shut it down?
For now, neither Kinney nor Squerciati has commented publicly, but their recent social media activity — liking each other’s posts and sharing cryptic couple-like quotes — has only added fuel to the fire. The One Chicago cast may never be the same after this relationship news breaks wide open.
