Ian Somerhalder-Nina Dobrev Relationship: Is 'The Vampire Diaries' Actor Cheating on Nikki Reed?

"The Vampire Diaries" actors Ian Somerhalder and Nina Dobrev are reportedly thinking of rekindling their romance, which fizzled out in mid 2013 after going strong for more than three years.

It is worth noting that Somerhalder is currently engaged to "Twilight" alum Nikki Reed, but there have been reports of "The Vampire Diaries" actor and his ex getting flirty on the sets of the vampire drama. The veracity of these reports is yet to be ascertained, and neither Somerhalder nor Dobrev has spoken about these claims.

But according to a new Celeb Dirty Laundry report, Somerhalder's relationship with his fiancée could be under strain, as it claims that Dobrev and Somerhalder are "sneaking behind" Reed's back. The delay in Somerhalder and Reed announcing their wedding date could be because Dobrev still has a shot with her former lover.

However, there have been rumours of Somerhalder and Dobrev planning a big wedding sometime in the near future.

"They do want an outside wedding and they also want it to be very intimate," a source close to the couple told HollywoodLife. "They definitely want the feel of it to be outside near where they live."

It is not immediately known who will be in the guest list, but fans are eager to know if Somerhalder and Reed will invite Dobrev to be a part of their big day, especially considering they were all friends before Somerhalder and Reed got together.

One of the reasons why Dobrev and Somerhalder called it quits was her hesitancy to settle down, but Dobrev has apparently had a change of heart after seeing Somerhalder with Reed, claims Celeb Dirty Laundry.

It remains to be seen if anything concrete will come out of the Somerhalder-Dobrev relationship drama, but their off-screen has apparently affected the ratings of CW's "The Vampire Diaries." The ratings have been steadily plummeting, with the most watched episode of the season being "Welcome to Paradise," and the least watched being Somerhalder's directorial debut "The Downward Spiral."
