"The show just didn't do well and it wasn't worth airing another season," a source told RadarOnline.
"The D.C. Housewives were meant to be starting shooting their second season now and they haven't heard a peep from Bravo. No one from the cast has been contacted yet and told that the show is canceled."
According to RadarOnline, Bravo decided not to renew The Real Housewives of D.C. -- which was the subject of controversy even before its debut, given the cast included alleged White House party crashers Michaele and Tareq Salahi -- due to its unimpressive first-season ratings.
"We're just hoping that people forget [The Real Housewives of D.C] ever happened," the source said.
In addition, the source reiterated Bravo executive and Watch What Happens Live! host Andy Cohen's recent comments that the network -- which had launched a total of three new The Real Housewiveseditions since in the last year -- has decided to stop expanding the reality franchise, which debuted The Real Housewives of Miami as its seventh edition last month.
"Bravo used to think it was about the brand and they could switch the Housewives at any point, but now they have realized it is about the women involved and that has changed their perspective," the source said.
"After DC failed in the ratings and Miami just bombed, they realized they can't just start a show anywhere and it will succeed."
