Nina Dobrev, Derek Hough Dating Rumors 2013: 'Vampire Diaries' Starlet Breaks Up with 'DWTS' Dancer? Reunion w/ Ex-Boyfriend Ian Somerhalder?

Though Nina Dobrev and Derek Hough were rumored to be dating for only about a month now, without a confirmation, it looks like this new couple is no more according to a source. The romance apparently "played itself out" considering the distance between the two. Though Dobrev and Derek's sister, Julianne have remained friends.

"Julianne understands - there are no hard feelings," a source explained. "The distance was too much to handle."

This brief romance came shortly after Nina and her Vampire Diaries co-star Ian Somerhalder had split after a long relationship. With Nina single again, some fans are hoping she and Ian get back together just like their characters in the hit CW vampire series.

In a recent interview with Cosmopolitan, Dobrev opened up about her love life.

"You either have chemistry or you don't, but a lot of what attracts me is a guy's mind and humor and talent," she said. "I need to get to know all those things before I fall for someone.

The 24-year-old actress added: "I'm not a one-night-stand kind of girl. I'm a relationship girl."

"I'm progressive in some ways, old-fashioned in others," she continued. "I like it when guys hold the door open and are sweet and thoughtful. The guys on our show are really good at that.

"A man in a suit looking put together and dapper is very attractive, but I also kind of like the I-just-rolled-out-of-bed, a-little-bit-of-scruff, effortless, not-trying-hard-but-still-sexy guy. If a guy spends more time looking in the mirror than I do, that's a problem!"

When do you think Nina will move on to another romance? Who do you think she'll move on with?
