Friday the 13th Piece Of Me Photos

Britney returned to the Axis Theater stage last night (February 13) to perform her 70th show at Planet Hollywood. Before she went on to sing and dance to her number hit '3' Britney told the crowd that she's feeling under the weather. It's the second time this week the pop superstar confessed that she's not feeling her best. Winter colds are the worst. Despite her feeling ill Britney soldiered on through the show much to her enthusiastic fans delight! Here are some photos from last night.
