Nick Cannon, Mariah Carey: We're All Good

Nick CannonMariah Carey and their twins were all smiles on Father's Day ... and Nick took a shot at the "haters" -- presumably us -- who have reported Mariah is at wits' end because he has dragged his feet signing docs that would make their divorce final.

The family, along with Nick's mom, hit up Sky Zone and there was no sign of drama.  As we reported, our sources say the custody agreement and property settlement were done deals more than a year ago and she has been pressing Nick and his lawyers to formally end the marriage, but it hasn't happened.

We're told Nick hasn't made any additional demands ... his side just hasn't pulled the trigger.  

But at least from the pics, it's all kumbaya.
