Tori Spelling is following in her late TV mogul dad Aaron's tiny footsteps and learning how to create lots of drama -- behind the scenes!

Well placed sources tell TMZ that Tori was a total terror while shooting promos for the second season of her Oxygen "reality" series, "Tori & Dean: Inn Love." We're told the new mom was more than two hours late to the set and would not interact with other actors. Post-partum aggression! Sources say Tori was annoyed by the cast because they "looked too good." Oh the gall! Apparently, motherhood isn't agreeing with her!

On-set sources tell TMZ that Tori then insisted she shoot her scenes separately from other actors and against a green screen. The "good-looking" cast were then forced to wait around for Tori's shoot to end, so they could begin to do their scenes against the green screen. All of which would be combined in post-production and edited to look like they were one big happy family. Hmmm. Sound familiar?

A rep for Tori told TMZ that there were two separate stages, and "Tori was on-set at 8:00 AM. The shoot was always intended to include the green screens. " As far as Tori saying the other actors "looked too good," Tori's rep added, "That is absolutely ridiculous."
