I think she is much to over the top to be an introvert. She is also pretty weird (yes, I am stereotyping, but she herself felt 'weird') so I say N.
I think she is an ENxP.
Introverts can be over the top if they find a way to express their inner thoughts through external expressions - an outpouring of some of the outlandish thoughts that inhabit their minds. Introverts can also sell a 'lie' as their image to fit in line with the greater target audience and sell more albums. This is what I think Lady Gaga consciously does - and does so pretty brilliantly. She has built up a stage personality for herself because it is much more sellable, not to mention makes her more enigmatic and magnetic. The perfect pitch, so to speak.
Ok - watched some of those videos. I seriously doubt she is an INTJ.
- There is an idealism and caring which she expresses that a young INTJ wouldn't have
- An INTJ would never have stayed in that restaurant; they would have walked out
- Do INTJs love to cook?
She seems very much like an NF to me. What about INFP? It would explain the idealism, visual artistry, immense creativity, and perfectionism.
She is an I_FP, but if you watch her interviews/read her interviews or simply look at her art and know what to look for, she obviously extroverts Se, not Ne.
INFPs introvert sensation and it's their 3rd function, as a result, they pay far less attention to any construction of sensory artifice than do ISFPs--Prince, Michael Jackson, Lady Gaga, etc. Unlike many ISFPs, INFP musicians typically make no distinction between appearance onstage and appearance off, to paraphrase Cobain on the adaptation of "gungewear" as a style in the early 90s, "these were the clothes we wore!" Their communication style and attention is far more diffuse and vague than is that of ISFPs; indeed, in interviews, INFPs will often deliberately avoid focusing on any specific loci (eye contact, for example) in order not to be overwhelmed by sensory material and to see the forest rather than the trees. While any specific sentence used by INFPs may resemble a sentence used by ISFPs, INFPs connect sentences/statements that are apparently disparate and random into a mosaic to paint a portrait of a concrete external whole (Ne)...
