On the set of their shoot, the Chicago Fire stars revealed that although the sizzling characters they play are fake — the dangers of working on set are extremely real. "You have this false sense of security with all your gear, but in the back of your mind it's always, 'We're playing pretend but the fires can burn you,'" Kinney admitted to ET.
And you can bet the stars' famous girlfriends would definitely be upset if anything happened to their fire-fighting beaus!
Kinney has been dating Lady Gaga for the past three years after meeting her on the set of her music video for the smash hit, "You and I." Spencer, on the other hand, is linked to pro surfer Maya Gabeira. The former House star has been dating the Brazilian beauty for the past two years.
