The `Born This Way` singer has visited the 31-year-old hunk on the set of his NBC TV drama show `Chicago Fire` a number of times and he was pleasantly "surprised" when she recently tweeted a promotion for the new series of the programme. He said: "I was surprised. I think she`s proud of, you know, girlfriend being proud of her boyfriend. She`s been to the set a couple times." While Taylor admits he is a "lucky guy" because he gets to date the 26-year-old star, he insists they would often spend a lot more time apart when he is on set and she is on tour if it wasn`t for the `Paparazzi` hitmaker`s secret weapon - a spaceship. Speaking on the `Today` show, he added: "For whatever reason, it works. I`m a lucky guy. "She hasn`t said anything, but she has a spaceship and she can get from A to B pretty quickly." Earlier this month, Taylor opened up about the couple`s relationship for the first time, describing it as "great". He said: "I don`t think I`ve ever said anything publicly up till now. But I`m happy. I`m in a relationship and I`m happy. Everything is great."
