Apparently one of the writers for the film in an interview admitted that in the original script, the characters were, in fact, gay lovers but other people working at Dreamworks bitched about, so they were forced to remove the pet names (which were going to be the implication that they were lovers), but pretty much everything else was kept, so technically… they are lovers. In the Spanish distributed version, if you put on English subtitles, the pet names are still there LMAOOOO
