Knowles: 'I Feel Sorry For Houston'.

Knowles: 'I Feel Sorry For Houston'.Pop beauty BEYONCE KNOWLES has expressed sympathy WHITNEY HOUSTON, saying she can't bear to talk about the downfall of the troubled superstar.The IRREPLACEABLE star insists Houston shouldn't be criticised for her battles with drug addiction and the breakdown of her marriage to BOBBY BROWN because she's had to cope with huge demands during her 20-year career in the music business.She says, "I once queued for Whitney's autograph when I was a kid. I had her photograph pinned up inside my wall and thought she was the very best around. I don't want to talk about what's happened to her since."I think it's very easy to get yourself into trouble. We live an unrealistic life in a crazy world. The demands are huge and the fallout can be equally big.You can get swept along by events. It is very hard for a woman in the music business to maintain a long term career. There are demands you cannot even begin to imagine."
