Bobby Brown is set to write a revealing book about his ex-wife Whitney Houston, it is reported.

The Huffington Post claims that the singer may cash in on the late singer's death because he needs the money.

Bobby apparently had a book ready for release in 2008 but because there was limited interest at the time for such a tome, the tell-all was never published.

But after the I Will Always Love you star died on February 11 aged 48 in the bathroom of the Beverly Hilton hotel, there is now renewed curiosity.

"Back in 2008, the interest in a book on Whitney Houston wasn't that great," a source told the website. "Whitney had fallen off the radar back then."

"But now, following her tragic death, the market has changed. Now is the time for a book that details an honest look into the life of Whitney."

Apparently Bobby may have signed a confidentiality agreement as part of his divorce with Whitney back in 2007 but it is rumoured he may try to find a way around that now that she has passed away.

"This is a man who left his ex-wife's funeral because he didn't like his seats and went to a paying gig that night," a friend of Whitney's stated.

"He didn't get on stage that night because he needed to sing his greatest hits or because Whitney would have wanted him to entertain his fans, he did it to get a paycheck - the same reason he now wants to write a tell-all book."
