Lady Gaga is so rarely seen with her boyfriend, Taylor Kinney, that fans sometimes forget that they're a couple. However, the singer and the "Chicago Fire' star are still going strong and have been together for three years.

On July 11, the "Born this Way" singer reunited with her man in Chicago and took to Twitter saying, "My boyfriend's back and it's gonna be trouble! Heyla heyla #chicago," she tweeted along with a picture of her in a white corset, black and white skirt suit, and multiple strands of pearls.

The next day, Gaga, looking very pretty in a pink sweater, shared an adorable picture with Kinney. She called him a "hero" in real life and wished him a happy birthday. The last time the couple posed for a picture together was back in May where they, and the singer's puppy Asia, posed in front of a mirror as the 32-year old actor held out his phone to take the picture.

Though their pairing is an unusual one, many people who are close to the couple claim that this is what makes it work. In an interview with Ellen DeGeneres, the singer called her boyfriend "extremely strange" but is "the best thing ever." Meanwhile, in an interview with E! News, Kinney said that he's "reserved, she's not. For whatever reason, it works."

Both seem to be very secure and happy in their relationship. In fact, Kinney's "Chicago Fire' co-star, Sophia Bush, said that Lady Gaga doesn't mind Kinney's romantic scenes with her on the show. "[Gaga is] an artist through and through. There's no part of her that doesn't understand our job or thinks it's weird. I think she's probably the least threatened woman on the planet," Bush said.
