The photos show Houston slightly heavier than what we've come accustomed too. The irony of course being that when she was extremely skinny, Houston was rumored to be on crack cocaine, and now, presumably at a more healthy weight, the rumors are she's pregnant. Despite the photo evidence, the chances of Houston being pregnant are slim. She is 47, making natural conception very unlikely.
Whitney Houston has not addressed the rumors, though a few theories of her weight gain have popped up. One is that she is being treated with steroids to combat a respiratory infection. Another attributes it to the side effects of becoming clean and sober.
She is already a mother to 17-year-old daughter, Bobbi, but do you think Whitney Houston is pregnant again?
