Page Six is reporting that Britney Spears only showed up to the set of her upcoming music video for "Pieces of Me" last Tuesday after her record label threatened to give the shoot to an younger, upcoming artist.

"Jive hired Wayne Isham to direct, had all the dancers there - hair, makeup and everything," our source added. "But she refused to come. Jive was really upset. They were already paying everyone overtime, and finally Britney showed up 12 hours late - but only after they told her they were going to give the video shoot to another Jive artist, Samantha Jade."

Anyone who has ever lived in a home with more than one dog knows that the only way to get a dog to eat something it doesn't want is to call the other dog over to feign interest. All of a sudden, that heartworm pill or celery you dropped on the floor looks damn appetizing to dog number one. So maybe all these authority figures and family members have been taking the wrong approach by appealing to Brit's sense of responsibility and guilt. I'm thinking what she really needs is a trip to obedience school. An "Invisible Fence" shock collar with a steady supply of Variety Snaps probably wouldn't hurt either.
