'Love & Hip Hop: Atlanta' Stars: We Got Fired & Job-Blocked by Execs

Two "Love and Hip Hop: Atlanta" stars claim they got the axe from the show but producers are refusing to give them walking papers ... so they can't pursue other work.

Margeaux Simms and girlfriend Merike Palmiste made their debut on season 4 of 'LHHA.' Margeaux's married to producer Nikko London on the show, but announced plans to move on with Merike.

We're told the twist in the relationship was supposed to play out on season 5, for which Margeaux and Merike already had signed contracts.

But a rep for both ladies tells us producers told them, shortly before taping began, they wouldn't be needed. The rep says they weren’t given an explanation. They also didn't get a signed release -- important to have because no other show will hire them without it.

Their lawyers fired off a letter to producers 3 weeks ago demanding the docs. We reached out to VH1, but haven't heard back.
