Nick Cannon and Christina Milian are back together ... at least on the dance floor of a Jamaican club in Queens.
The former flames were spotted at a joint called Lorna's for Seafood Tuesday. We're told they showed up around 1:30 AM ... cut a rug for about an hour and took off.
Nick and Christina were out with a group of friends -- but we're told they're not back together. Check out "The Wendy Williams Show" clip ... Christina seems to leave that door open a crack.
