I thought this article was interesting, esp. since Jennifer seems nice:

But I have noticed this season that even Pros like Tony and Mark have made a few remarks on this issue. Tony seems upset since he knows he has a contender in Audrina and Jennifer is her #1 competition.
P.S. Did anyone notice that Jamie Lee Curtis is often shown in the background when Jennifer dances? Are they friends, or is it just coincidence? Wasn't sure if there's a movie they are in together or some other connection.
