There's nothing like a little competition to get someone motivated. According to the New York Post, Britney Spears was ready to bail on her $500,000 music video, but showed up when she learned that her record label was ready to let an up-and-coming singer have the shoot. "Britney was supposed to shoot a video for her song 'Piece of Me' last Tuesday at Social Hollywood," a well-placed insider at her Jive Records label told the paper. "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." At least there's something that will get Brit to work!
