The Chicago Fire star reveals the couple enjoys a range of hobbies together, from taking scenic walks to expressing their artistic sides.
However, Kinney often finds himself poking fun at the Born This Way hitmaker for choosing outfits that are completely unsuitable for their planned day out.
He tells Glamour magazine, "I'm always giving her flak, like, 'Babe, you can't wear your heels when we're hiking'."
Kinney adds their relationship is built on a shared sense of humour, saying, "There's a lot of laughing. I think that's the basis of a healthy relationship. We laugh a lot. I think we just complement each other. I'm proud of her, and I'd like to believe she's proud of me. We're kindred spirits."
