A picture taken on April 7, 2010 in Neuilly-sur-Seine, shows the American Hospital in Neuilly, a clinic in a chic Paris suburb favoured by French celebrities. American pop diva Whitney Houston was being treated for nose and throat problems in the American Hospital today, after cancelling the first European date of her troubled comeback tour. The 46-year-old, whose hits in the 1980s and 1990s included "I Will Always Love You" and "I Wanna Dance With Somebody", had been scheduled to play a gig in Paris on April 06, 2010 but cancelled it at the last moment.
