This is different though, this isn't your normal 14-year-old girl texting your normal 31-year-old man; right or wrong, this is two folks in the industry, who move in similar circles, one of whom may be a teenager but is surrounded, works and has relationships with grown folks on a daily basis, and like most teenage stars has a mentor, publicist, agent etc who know and advise her about her working and private lives. It's understandable that networking of this nature exists in this sphere (especially if they're fans of each other's work), regardless of age.
The dilemma here is if lines are being crossed, which given the context we really don't know.
