Before Tiger Woods famously hit a fire hydrant last November, gossip headlines were saturated with Jon and Kate Gosselin drama.

Things have calmed down a bit since then, but now that Kate is going to be showing off her dance moves on the upcoming season of “Dancing With The Stars,” it looks like ex-husband Jon has a thing or two to say about her shining spotlight in the celebrity world.

Sources say that Jon is “concerned” about Kate competing on the show because of the time it will take away from her with their eight children. A source says, “Jon’s angry because doing ‘Dancing With The Stars’ will keep her away from the kids for days, and she still won’t let him have any extra custody.”

We smell a little case of jealousy here.
