Crew members on the hit Fox show Empire are labeling guest co-star Nia Long a diva after a series of events took place during the star’s appearance on the drama.

It’s hard to think of Nia as anything less than magical and sweet, but according to sources working on Empire, Long was disrespectful and unprofessional during her run. Now, cast and crew claim they don’t want to work with her again. Yikes.

Sources tell TMZ that one of the several occurrences that took place during Long’s time on the show is when the actress went HAM on hair and makeup because she didn’t like the look. Nia’s flip-out in hair and makeup allegedly caused the team to file a complaint against the beauty.

There had also been previous reports claiming Taraji P. Henson started beefing with Long over how she treated the staff.

Sources also tell the news outlet that Long, a mother of two, was “habitually late.” It got to the point where producers were forced to use stand-ins so Terrence Howard and Taraji could rehearse their scenes. Per the insider, she was regularly at least 30 minutes late.

And finally, the major kicker: According to reports, Long was livid that producers didn’t say goodbye after shooting her final scene. Sources claim the actress threatened to file a lawsuit over not being properly released. (For all you actors out there, you’ll know it’s often standard for the director or assistant director to call the star’s name and thank them as they wrap their final scene.)

Nia’s reps, however, are calling bs on all the stories. They explained in a statement that “We stand by our comments this morning that Nia has always, and continues to be, a consummate professional on set. In respect to her working relationships with the cast, she came onto this project, in the first place, because of her long-standing friendship and professional relationship with Terrence Howard.”

The statement added, “We are not aware of any complaint, suit or case against her from anyone involved in the show, and we find the timing of all of these stories to be very suspicious, given that the series returns tonight.”
