Well you could just try to Facebook search her, or if you have Zach as a friend, look through his friends list. Or try Google searching her. There are ways to research this if you are really dedicated to finding that info out.
Frankly, I don't see this as any big deal to chatter about. Within a short bit of time I'm sure we'll know more if you care to follow her uploads. Anything else just seems almost like tabloid level chatter on who she is, what her qualifications are, is she dating him, etc.
Maybe it's just me? I'm known to not be star struck as it were, and sorry in advance if I'm a kill joy on this.
