There's no doubt that Madonna is having a very hard time with her very public custody battle with ex-husband Guy Ritchie over their 15-year-old son, Rocco. After the teenager refused to board a plane from London to New York City to spend Christmas with his famous mother last month, Madonna has gone into what many critics would describe as meltdown mode.

Now, fans are reporting that the chart topper might have referred to her ex-husband using a derogatory female term during her concert in Nashville last week. Some critics are hinting that Madonna is afraid that her son might end up living with his father full-time if she keeps this up.

According to Celebitchy, when as fan asked the Material Mom to marry him, she dropped the C-bomb on him. She allegedly said, "You are... a c---? Okay. I'm not sure what I'm supposed to do with that information. I'm looking for a husband, not a c---. I already married a c---."

And to make things worse, Madonna apparently used a "hillbilly" accent, which irked a lot of her fans in the audience.

So far Madonna hasn't made any public comments about her custody battle, but it doesn't look like Rocco is coming home anytime soon. The young boy has already missed almost a month of school as he's been living with his father and his family in the British capital. Guy for his part hasn't said anything, either.
