Lady Gaga was introduced to her boyfriend Luc Carl's parents over Christmas, which made things appear to be getting more serious between the singer and her beau. That's not the case though.
"Gaga and Luc are fighting a lot," a source close to the couple told Life & Style. "Their relationship has never been perfect -- it's always been tumultuous -- but now it's hanging by a thread."
If things are bad between Carl and Gaga, they're not much better between Carl and Gaga's friends, as the source claims that he's made "zero effort to get to know them."
The couple's been together, on and off, since 2005, and Life & Style's source suggests that "he's using her because of how famous she is. He doesn't treat her very well."
