R&B singer Whitney Houston recently turned her life around and she refuses to let anyone destroy her hard work, not even her ex-husband Bobby Brown. In his latest venture, Bobby Brown is trying desperately to release his Bravo reality show “Being Bobby Brown” on DVD, but Houston, who appeared heavily in the series and seemed to be under the influence during most of the filming, refuses to sign the papers. “Whitney blames the show for ruining her career and she won’t sign off on the contract to release the DVD,” Brown tells In Touch magazine. “There’s a lot of money to be made, but, because she won’t cooperate, we’ll never see it. I have a serious problem with that because it affects my income.”
