Taylor Kinney says he falls in love with someone's "energy" rather than their looks and insists he doesn't have a type.

The 'Chicago Fire' star - who ended his engagement with Lady Gaga last year - insists he doesn't have a type and instead sees compatibility as "the intangibles of something".

He quipped: "My dating life is through 'Chicago Fire'. I live vicariously through my character."

Before adding to Entertainment Tonight: "I don't think I have a type. I think it's more of an energy. I think of compatibility as the intangibles of something, and someone that you meet and connect with, and someone you can laugh with, and maybe share a [simililar] sense of humour, then things go from there."

Meanwhile, Lady Gaga previously admitted she wouldn't be happy if Taylor started dating someone new.

She said: "I hate to sound like a hippie, but I kind of am one and so is he. We love each other, that's it. It's just about life changes, and we all go through different stages and we're focused on different things.

"To be fair, I think that Taylor's pretty f***ing cool that over the years no matter what creative transformation that I've gone through, he's always been very supportive of that and loving . I'm not going to f**king throw a party [if he gets into a new relationship]."

The pair were together for five years and engaged for one before they ended their romance but Gaga has previously insisted they are "soulmates".

She wrote on Instagram after their split: "Taylor and I have always believed we are soulmates. Just like all couples we have ups and downs, and we have been taking a break. We are both ambitious artists, hoping to work through long-distance and complicated schedules to continue the simple love we have always shared. Please root us on. We're just like everybody else and we really love each other (sic)."
