Yes, Liz Rosenberg has been Madonna's publicist, and according to her, some sort of "surrogate mother" since 1984. Madonna always pays homage to her whenever she can. I also remember that, besides playing a character named "Liz Rosenberg" on that SNL skit, Madonna's character on WILL & GRACE (in 2003) was also named…

It's actually quite funny how you failed to understand what Madonna was doing last night. I mean it, it's very amusing, and that explains why she's kept the world so captivated by her for such a long time.
