'Dance Moms' -- Banned From Dance Competition

The producers behind the Lifetime reality show "Dance Moms" have been banned from one of the biggest children's dance competitions in the country ... after event organizers complained about the way the event was portrayed on the show last year.

"Dance Moms" is a show about intense mothers who enter their young daughters into dance competitions ... and during Season 1, the second episode focused on a HUGE competition in Pennsylvania called StarQuest.

TMZ spoke with SQ associate producer Michael Ian Cedar who claims producers did not air the true results of the competition ... and edited the footage in a way that misled viewers into believing certain dancers were competing against each other .... when in fact they were not.

Cedar also claims "Moms" producers misled him into thinking the show was about young girls in the competitive dancing world -- not about their catty foulmouthed mothers.

Despite SQ's grievances, Cedar tells us "Moms" producers once again reached out to SQ ... hoping to feature a StarQuest event on Season 2. Cedar claims he shot down the request.

TMZ spoke with "Moms" producer Jeff Collins ... who brushed off Cedar's editing allegations as "nonsense" ... adding, "We're sorry he feels misled ... we'd love to work with StarQuest again."
