Second Opera Post of the Day: A Duet

If you are any kind of a Verdi fan, you know that one of the unmatchable show-stoppers is the second-act "friendship" duet in Don Carlos.  But do women ever get to do anything like that?
Maybe not quite, but here is one reasonably plausible contender.  It's from Donizetti,the second act of Anna Bolena.  Not exactly a "friendship" episode, because here is where Jane Seymour tells Ann that she will be Ann's successor as the (third) wife of Henry VIII.  Anna adorns the resume of several great names; here she is in the rendition of Anna Netrebko, with Elīna Garanča.
