Nina Dobrev, Ian Somerhalder Split? 'Vampire Diares' Stars Break Up After Three Years (Report)

"Vampire Diaries" stars Nina Dobrev and Ian Somerhalder have reportedly broken up.

Us Weekly reported Thursday that Dobrev and Somerhalder have split after three years. Despite the fact that they work together, the breakup won't cause any issues. They are "consummate professionals," a source told the magazine, and "will continue to work together and remain best friends, which is where the relationship started."

People magazine also confirmed the Dobrev-Somerhalder split with a source.

A publicist for Dobrev told The Huffington Post the company does not comment on clients' personal lives. A representative for Somerhalder could not be reached for comment at the time of publication.

Whether or not Dobrev and Somerhalder have split for good is unclear, but what is clear is the amount of time she has been spending with newly single Julianne Hough, who broke up with beau Ryan Seacrest in March.

The two starlets were spotted vacationing together in Miami in late April and then met up at the Met Gala on Monday (sans Somerhalder). Have they been celebrating singlehood?

The 24-year-old "Vampire Diaries" beauty and her handsome co-star met on their CW set in 2009, started dating the following year and went public with the romance in 2011, Life & Style magazine notes.

Last November, she spoke with Glamour magazine about making a relationship work.

"Every woman wants and needs different things," she said. "It's always best when you're honest and you speak up. It's hard to read minds."
