(BANG) -
Lady Gaga's boyfriend Luc Carl dumped his girlfriend to get back together with the pop star.
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."
