Taylor Kinney has denied he is engaged to Lady Gaga, saying, "It's news to me."
There had been rumours that the Poker Face singer and the 31-year-old actor were planning their wedding, but he batted the stories away, saying he is unaware of the reports that he had popped the question.
He told Extra: "It's news to me! You probably know more about it than I do."
The couple have been dating ever since meeting on the set of the singer's You and I music video in September 2011.
Taylor - who stars in American TV show Chicago Fire - said he would be open to Lady Gaga (whose real name is Stefani Germanotta) appearing on the show.
"Yeah, we could do that. She'd have, like, fire-breathing breasts," he joked.
The actor also revealed that she is on the mend since undergoing hip surgery, saying: "She's great, she's doing well."
