The Gaga’s boyf Luc Carl dumped his gf to get back together with the singer…apparently.

The New York-barman has been close to Gagaloo – real name Stefani Germanotta – for four years, and the pair rekindled their love-fest after she returned to the ‘Big Apple’ to visit him last month.

A friend of the 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.”

The pair first met 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.

The singer has also flown Carl out to join her on her ‘Monster Ball’ tour in Houston, Texas.

One person not overly keen on the re-hook-up, is Carl’s Mamma, Melinda, who told The Daily Mirror:

“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.”
