Madonna Has Tough Time Lecturing ‘Lost’ Britney Spears

People magazine reports that when Madonna and Britney Spears met up for the NRJ Music Awards in Cannes, France last week, the Material Girl gave Britney a sisterly but stern lecture about her behavior, including her quickie marriage and how to take better care of herself. “The lights on but no one’s home,” said a source who was there. “[Britney is] such a sweet thing but so lost.” It wasn’t the first time Madonna gave frank advice to Britney. At their MTV Video Music Awards rehearsal, Madonna warned Britney about her smoking habit. “I like the way it makes my voice sound,” said Spears. “Do you think you’ll like cancer?” Madonna replied.
