According to my inside sources, Brandy Norwood is throwing her former duet partner Monica Brown under the bus after their single “It All Belongs to Me” failed to meet expectations.

And now their upcoming tour has been scrapped. But Brandy is placing the blame for the failed tour squarely on Monica, saying Monica is more focused on her sons and husband, Shannon Brown, than she is on touring.

But that’s not true, according to my source. He told me there were issues with the top billing (whose name would go first) as well as money issues (who would get paid more). He said Brandy derailed the tour by demanding top billing and more cash upfront.

“It’s a done deal. And [the deal] fell through,” said my source.

In an interview with Barkbiteblog, Brandy said:

Um, honestly, we haven’t really talked about it since we stopped promoting “It All Belongs to Me.” I just honestly think Monica and I are in different places in our music. And my vibe is a little bit different this time around so I don’t know. I kind of wanna do my own thing. I definitely feel like the fans would want a tour from us, but I don’t know, I just feel like I’m being pulled in a different direction. I’m definitely still open to it, but right now I’m looking in a different way right now for me.

The insider pointed to the lackluster sales for the single, and for Monica’s album New Life, as some of the reasons why Brandy wanted to pursue other options, such as recording album features with other artists rather than go on tour with Monica.

“Brandy thinks she is a bigger brand than Monica,” said my source. “She has more shows than Monica, she was the star of Moesha.”

Last month, the same source told Sandrarose.com that Brandy and the label were using Monica as a promotional tool for Brandy’s upcoming album. It looks like he was right after all.

As I told you in THIS post, the record label was much more interested in pushing Brandy’s project than Monica’s. I can’t go into any details on that.

But rest assured that Brandy’s album will flop because the same people who worked hard to promote Brandy are now the same ones she is walking all over. (Read between the lines).

“Brandy is disingenuous in everything she does,” said a record label source who begged for anonymity. “Brandy and her brother [Ray J] use people for their own benefit.”

“What makes Monica a safe bet for her fans is she’s real. If you’re going to be real, be 100% real,” he said.
