I think it is sad that she even asked about her single or not status. An individual is so much more than who or who they are not dating, or even IF they want to date.
The reporter had a chance to interview an Olympian who just performed an incredibly intensive dance routine as part of a dancing show. WHY would she ask about her dating life? It has NOTHING to do with her performance. Before interviewing any female (performer/singer/athlete)-interviewers should ask themselves, "Would I ask this question if I were interviewing a man?" and if the answer is "no" - don't ask it.
