LONDON: Madonna's daughter Lourdes doesn't want to wear skimpy outfits like her mother. The 'Celebration' singer's daughter - who turns 13 on Wednesday (14.10.09) - has vowed never to wear flesh-flashing outfits like her pop star motherbecause she would feel too embarrassed. A family source told Britain's Hello! magazine: "Lourdes is fairly conservative. I recently heard her say she would never be comfortable wearing some of the costumes her mom wears on stage. 'Oh that is so not me,' she said." Despite not wanting to don outrageous costumes,Lourdes - who recently appeared in Madonna's 'Celebration' music video wearing a mock-up of the pop superstar's iconic 1984 'Like A Virgin' outfit - often rows with her mother about her fashion choices. A source explained: "Occasionally, they argue because Lourdes might like to wear something hermother doesn't agree with. "Like all mothers and daughters, they have disagreements. That's OK with Madonna. Madonna told me, 'I want her to learn to argue and stand up for herself. And if she can stand up to me, she can stand up to anyone.' "
