Lady Gaga sure knows how to rekindle the flame!

According to a source, singer Lady Gaga and her ex-boyfriend Luc Carl are back together again…and this time she’s convinced it’s for good. The two started back dating after Gaga invited Luc (who at the time had a girlfriend) to a New York Mets Baseball game back in June. Not too long after finding out the “Alejandro” singer was still interested in him, Luc dumped his girlfriend (a hot blondie) and hopped right back on the Gaga train.

“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,” the source says. “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, we hope this time around works out for ya…
