I remember this dude that use to be around them both during the IABTM era. He said behind the scenes it seem like Monica would always irritate Brandy. He also said there was one interview that Brandy was upset with Monica about and actually told her afterwards that she was doing too much, she needed to talk to her first before she just running her mouth about the past and that she was being too ghetto. Monica didn't take that well and it's sparked a very heated agruement. Thats when they was done with the song and each other. Then he said about two years ago that Monica claimed that Brandy was blocking her credits on that girl is mines song and that Monica was talking shit about it and that it got back to Brandy and that was the last straw. Also he said people behind the scenes thought it was crazy how competitive they was over who was closer to Whitney.
I don't know if that was all true but he did use to be with them. He use to send pics with them always around him but yea....
