Khloe Kardashian and Tristan Thompson are essentially operating as one parental unit, but that doesn't mean they're romantic again ... despite growing speculation online.
Sources close to the two tell us they're still operating as they have been for months -- as co-parents -- but Tristan lives near Khloe's place, so they're spending a lot of time together. Remember, they now have two young kiddos, and we're told it's important to Khloe that the kids get to spend as much time with Tristan as possible.
