Rumors have it that the "The Vampire Diaries" stars are getting back together after reports emerged that Nina Dobrev and Ian Somerhalder are dating again. Despite news about their reunion as couple, "The Roommate" actress' ex-boyfriend is now engaged to Nikki Reed and she is not invited to attend the ceremony.

According to Celebrity Dirty Laundry, Nina Dobrev and Ian Somerhalder dating news are true as a source confirmed that they are getting closer again at their set in Georgia.

"After remaining distant and awkward for the longest time, rumor has it that both Nina Dobrev and Ian Somerhalder have slowly started to get closer and more intimate on the set of The Vampire Diaries," the insider spilled.

The 27-year-old actress even fueled rumors that they are together again when she posted a photo in her Who Say account showing "The Anomaly" star in a tutu shirt.

The two seemed to be having fun while on the set, which immediately prompted speculations that the former couple are seeing each other behind the "Twilight" actress.

Meanwhile, Nina Dobrev is reportedly not invited to the wedding of ex-boyfriend Ian Somerhalder and fiancé Niki Reed.

Because of reports that Nina Dobrev and Ian Somerhalder are dating again, having the "Perks of Being a Wallflower" actress at their wedding might allegedly terrify Nikki Reed.

According to CDL's report, Nikki Reed is "getting worried" on their budding closeness.

An insider from Hollywood Life also told that the future husband and wife are arguing about whether they would invite Nina Dobrev or not.

"It's a very weird predicament for Ian and Nikki. If it is a big wedding Ian feels that he has to ask Nina to go, but anticipates her to respectfully decline. That would be a win win," a source said.

"The Anomaly" actor Ian Somerhalder began dating the "Twilight" actress a year after his split from Nina Dobrev.

Shortly after six months, "The Vampire Diaries" actor proposed to Nikki Reed that she announced early this year.
