Britney Spears was left red-faced during a 14-minute concert in Florida last night (19May07) when her backing tape skipped revealing once and for all the pop superstar is lip syncing her comeback. The Toxic singer was performing her fifth return show at Orlando's House of Blues when the incident happened, forcing the singer to look away as technicians raced to get the tape back on track. The pop star and her M+M's dancers took to the stage at 9.30pm local time to perform for the sell-out crowd, and opened the show with her classic ...Baby One More Time. Unlike the series of concerts she performed at House of Blues venues in California and Las Vegas earlier this month (May07), this show didn't go quite to plan. But despite the brief musical mishap, Spears looked like she was having great fun onstage. She ended the set with a shortened Toxic and then parted after telling the crowd, "Thank you so much for being here. You're awesome. I love you!" As WENN went to press, Spears was set to perform a second Florida show in Miami (20May07).
