I can confirm it. I caught their segment right before I left for work; it started at around 8:45 am Eastern time. They were interviewed by Robin Roberts, and there was an impressive display of fragrances that she said belong to Diane Sawyer (apparently Diane is a kindred spirit of ours -- who knew?).
In keeping with the general audience for the program, most of the questions Robin asked were pretty basic, e.g., "What's the difference between eau de toilette, eau de parfum and parfum?" She did touch on L & T's disagreement on the "personal chemistry" issue -- Luca thinks a scent will smell pretty much the same on everybody, while Tania says that perfume shopping with other women has taught her otherwise.
