Nina Dobrev and Ian Somerhalder’s breakup fallout has reportedly led to Somerhalder’s new girlfriend, Nikki Reed, being banned from the Vampire Diaries set.

Breakups are never pretty, but the Dobrev-Somerhalder breakup could affect the future of the popular series.

Hollywood Life reports that producers are worried that Dobrev may leave The Vampire Diaries after Season 6, alleging Dobrev is having trouble dealing with the on-set PDA between her ex and Reed.

Dobrev is allegedly more than a little annoyed by Reed’s presence on set while she’s trying to work. Fans seem to totally relate to Dobrev’s distress at having her ex-boyfriend’s new girlfriend there while filming emotional scenes.

“Ian and Nikki’s relationship is causing a lot of drama, to the point where the producers have asked Ian not to bring Nikki to set when Nina is there because they are very worried about losing her. They worry that the show would fall apart without her,” a source told Hollywood Life.

Sources also say producers are bending over backward to keep Dobrev happy on set, because they’re afraid she’ll give up and call it quits after season 6.

“It’s unlikely that Nina would try to get out of her contract in the middle of this season, but it’s something producers are worried about. It would be very costly for Nina to get out of her contract now, but things like that have happened before, so everyone’s walking on eggshells with her. Not to mention the fact that Nina hasn’t signed anything for anything beyond season six,” a source told the website.

Apparently, Somerhalder is so taken with Reed that he is completely blind to how much his new relationship is hurting Dobrev.

Naturally, the producers — who tried to keep Dobrev and Somerhalder from dating in the first place — are now said to be upset by the entire situation, thinking that it could cause irreparable harm for the future of The Vampire Diaries if Dobrev walks out.

“This is exactly why producers actually tried to forbid Nina and Ian from dating,” said the source. “They were worried something like this would happen. Ian and Nina tried to hide their relationship for so long because they were very strictly forbidden from that, but obviously they did go there. Exactly what they promised wouldn’t happen, has happened, and it’s getting in the way of their work.”
