If you're wondering why Octomom's Facebook, Twitter, and Ustream accounts have all been suddenly deleted ... it's because the mother of 14 has just been dropped by her management team -- TMZ has learned.
Sources close to Nadya Suleman tell us, it's all because Octo was the ultimate flake -- her management team would book her on paying gig after paying gig ... and Nadya "would find any reason" to cancel last minute ... often claiming she couldn't find a babysitter.
We're told Octomom was great the past year -- raking in lots of dough through appearances and different celebrity events -- but getting her to work the past couple months has been like pulling teeth.
By the end, we're told it was nearly impossible even to reach Octo by phone -- and her managers had just about enough ... so they dropped her this weekend.
We reached out to Octomom's now-former manager Gina Rodriguez -- who replied, "I quit on her because she is unmanageable. She would not reply to anything work-related we would call or text about especially if it was not paid."
Gina added, "Regardless of the $70k we made her, she still claimed to not be able to pay any of her bills. We no longer wanted a part of any of it and we feel sorry for the children."
