Britney Spears narrowly missed being replaced on the set of her own music video by a younger rival, according to US reports. The troubled singer was set to film a $500,000 video for her new single, Pieces Of Me, but failed to show up on the day of shooting. An industry insider revealed, "Jive hired Wayne Isham to direct, had all the dancers there - hair, makeup and everything. 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... Britney finally showed up when she realized a new, younger, hotter girl would take her slot."
