Pop star Britney Spears angered organisers of the Teen Choice Awards on Sunday (20AUG06) by refusing to get rid of her chewing gum before going onstage. The heavily pregnant singer made a special guest appearance in a pink baby-doll dress at the end of the show to introduce husband Kevin Federline's debut rap performance. Spears received widespread criticism in June (06), when she was interviewed by TODAY show host MATT LAUER wearing revealing clothing and chomping on gum throughout the interview. According to an awards-show source, "We told her to spit out her gum, but she refused."
