Booty Rub on You Think You Can Dance?

OK, I caught like the last 10 minutes of "So You Think You Can Dance?", where it was down to the final 4 contestants. I don't watch this show in particular, I was just browsing channels and happen to catch it. Well, I could not help but notice that during the judges final comments on their performances, the dancer named Joshua, was constantly rubbing on the host's booty the whole time. At first I was like ... what is he doing? Then as the judges kept on with their summations and comments on their latest performances ... the booty rubs just kept going. I'm sure the host didn't want to make a scene, but dang! It's like that on the show? I just thought I'd make note of this since I'm bored and wanted to write something on the site.
