New York-barman Luc has been close to Gaga - real name Stefani Germanotta - for four years, and the pair rekindled their romance after she returned to the `Big Apple` to visit him last month. The `Alejandro` singer was unaware Luc was dating someone else when she went to see him and the hunk ditched his other love when he knew Gaga was interested in him again. A friend of the `Poker Face` singer`s said: "Luc was like the cat that got the cream. He had the most famous woman in the world vying for his attention and a hot young blonde waiting in the wings. "It could have ended really badly, but the other girl melted into the background. She knows what Luc`s like - he has women all over the place... Gaga has convinced herself that this time she`s got Luc back for good. "She says it`s serious and that, after a few false starts, she thinks they are back on for good." Gaga first met Luc when she was working in New York club St. Jerome`s in 2006, but rekindled their friendship when she invited him to a New York Mets baseball game in June. Since then the pair have been "together", with Gaga even flying Luc out to join her on her `Monster Ball` tour in Houston, Texas. However, Luc`s mother Melinda is not over-enthusiastic about their reunion, because the relationship ended badly last time. She told the Daily Mirror newspaper: "They had a very nasty break-up last time. And I have no idea how this will end. I deliberately haven`t talked to him about what`s going on. With those two, you never know."
