MADONNA may be an international pop icon and singing star. But when one of her children is upset she is simply just a mother that would do anything to comfort them. And that was the case Sunday when a tearful Lourdes walked out of the Kabbalah Centre in New York looking very sad. The 14-year-old was apparently not feeling very well and her face was crumpled. Wearing blue sweatpants, a matching shirt and denim sleeveless jacket, the teen appeared like she was talking out her issue with her mother. Madonna placed a protective arm around her eldest child and ushered her towards their vehicle. The Material Girl was dressed youthfully in tight light brown trousers, a matching top with a longer sleeved white shirt underneath. She covered up with dark glasses and a newsboy cap and wore black ankle boots. Also attending the service but looking decidedly more cheerful were Madonnas younger children, Rocco, 11, David, six, and five-year-old Mercy. Both boys were dressed all in white. Madonna has been a follower of the controversial religion for several years and said 'all the puzzle pieces started falling into place when had a spiritual awakening with Kabbalah. 'I heard what he had to say and I knew at this moment my life would never be the same, she said of her first Kabbalah class. 'Life no longer seemed like a series of random events. I also began to see that being rich and famous wasnt going to bring me lasting fulfillment and that it was not the end of the journey. DM
