London, April 8 (Inditop.com) Singer Whitney Houston is out of hospital and has hit back at reports that she is back to taking drugs.

The 46-year-old sparked health concerns when she was forced to scrap a string of European concerts after she was diagnosed with respiratory problems. She was rushed to Paris hospital for treatment.

Contactmusic.com reports that rumours were rife that Houston has started taking drugs again. However, she now insists that allergies sparked her medical problems, not a relapse – and calls the stories about her drug use “ridiculous”.

“At this point, I just don’t respond. I don’t even read,” she said.

She also revealed her health is terrific and she can’t wait to resume her tour in Birmingham, England, April 13.

“I’m just ready to move on and continue my world tour. I’m doing what I love to do, which is singing. The best part is seeing all of my fans around the world,” she said.
