Jennifer Lopez has scrapped the final show in her first-ever concert tour to get an early start on impending motherhood. The pregnant singer and husband Marc Anthony postponed the 24 October (07) San Diego, California show as a mark of respect to those left homeless by the state's devastating wildfires. But now the show has been cancelled altogether because of an unspecified "scheduling conflict." A press release issued by the concert's promoter Live Nation reads, "Unfortunately, rerouting the tour has been impossible due to the event's last-minute postponement caused by the area wildfire emergency." But local newspaper the San Diego Union Tribune reports poor ticket sales and Lopez's pregnancy are more likely to be the causes for the cancellation. Lopez's tour designer Roberto Cavalli revealed the worst kept secret in America last month (Oct07), when he explained how difficult it was creating costumes for a mum-to-be.
