Gaga, 26, has been dating the "Vampire Diaries" star for a year. Kinney, who is promoting his new TV show 'Chicago Fire', said he is lucky to have the singer in his life, reported Daily Mail.
"I don't know, because I don't have that outside view. It's normal, if you will, in that respect. We're just normal! I'm a happy guy. I'm a lucky guy," he said.
Kinney said that Gaga has been very publicly supporting his new project, in which he stars as Lt Kelly Severide, by tweeting her love of the show.
"I was surprised. I think she's proud of, you know, a girlfriend being proud of her boyfriend. She's been to the set a couple of times," he added.
