American actor/model Ian Somerhalder and Nikki Reed are reportedly planning to invite his former girlfriend, Nina Dobrev to their wedding.

According to Hollywood Life, the couple want to share "their happiness including his work family — The Vampire Diaries cast and crew" which includes the 26-year-old actress, who plays Elena Gilbert on the supernatural show.

"It's a very weird predicament for Ian and Nikki," the source said. "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."

Dobrev and Somerhalder, who are co-stars on the hit television series, dated for more than three years, before splitting in May 2013.

It was previously reported that Dobrev was devastated over the engagement news.

"They may actually dodge future awkwardness by having a very intimate wedding with just family and then they can make the excuse that they didn't invite any cast members. One thing for sure is that it is a problem they are definitely trying to figure out," the insider added.

Somerhalder and Reed were first romantically linked last year in July after they were spotted shopping at the Farmer's Market in Los Angeles.

Later, the 36-year-old actor confirmed their relationship on Instagram when he lashed out at a few of his fans for bashing Reed.

Meanwhile, the couple may take their wedding vows in June.

"They mentioned a June [wedding] date," a source told InTouch magazine. "They're really excited."
