Gaga took a dig at Madonna during one of Gaga's shows and on twitter as well.
Gaga can't attack everyone that criticizes her. She's not...Hmm. Anyway, Gaga has only rarely targeted artists (Calvin and Die). She didn't say anything bad about that girl from 2008 (can't remember her name) that didn't know if Gaga was male/female.
Don't look so deep into it. It's Gaga and her friends with their own minds. Gaga is full of life and has the right to have these people in her lives
