I know Debbie is friendly with Ginetta the Veronese guest, so she probably has picked up a few words and phrases during her visits over there. If she's got a knack with languages, she may have more than a few words and phrases. If she becomes really proficient, maybe she'll be able to head across to QVC Italy for a stint. I know some German and Italian brands coming to QVC over the years have had QVC presenters coming to UK as the brand ambassador. I seem to remember the dream styler (the hairbrush curler thingies) was presented at least some of the times by a QVC Germany presenter (current or past).
The guest who appears for Bella Vita and Bronzo Italia was complimenting Catherine Huntley on her Italian accent the other day in a BV show. It sounded good to my ears, and the guest sounded thrilled (probably used to lots of people mangling the language).
