MIMI FAUST and NIKKO SMITH from the reality show "Love & Hip Hop:  Atlanta" have a sex tape ... and it's going on sale next Monday.  The STORY is that the porno company Vivid.com got a hold of it, and got Mimi and Nikko to sign off on it.  The producers of "Love & Hip Hop" also gave their blessing.  Of course, it's more likely that this was planned from the beginning.

Check out some pictures here.
