Has Celebrity Gone to Jon's Head?

Millions of people tune in to Jon & Kate Plus 8 every Monday. In fact, 4.6 million tuned in to watch the series' season 4 finale: the finale that announced the possibility of no fifth season...ever.
Since Star magazine published an article about Jon's alleged night out in which he partied "the night away with a bevy of college cuties," speculation and disbelief have run rampant.

In the show's four seasons, Jon has never once alluded to any sort of dissatisfaction. In fact, he always seems to be cheerful, even when he is being hen-pecked by Kate. During some of the "All You Wanted to Know" specials, viewers even e-mail in to ask for advice about parenting.
True, Jon has used his celebrity in the past for aesthetic gains. In March 2008, Jon received a hair transplant to fix his premature balding.

But is a man's desire for hair proof of discontent?
Jon's alleged night out with co-eds may not be true (in fact, other than a couple of college girls, there is nothing to back up the story- especially no pictures), but it has certainly taken a toll on his life (and the show). In fact, in an article in EW , readers learned that the show was taped just as accusations of Jon's exploits surfaced.
