The source, who is close to Bravo, says the celebrity stylist was pissed over Brad's feature in the New York Times style section when he doesn't have a publicist. Rachel's got two publicists working for her and has yet to get that kind of press in the Times.
The Bravo insider adds "I don’t believe for a second [Brad gave notice] a month ago" because that info would have been announced much earlier.
Also, some people believe the pregnancy rumor was used as a distraction from this messy split.
That wouldn't surprise us one bit.
