Rumor has it that the 'Vampire Diaries' star Nina Dobrev has a new "secret boyfriend" according to several news reports. The actress has been speculated to be dating her ex-boyfriend and 'Dancing With the Stars' dancer Derek Hough.

After being spotted at several parties, news reports speculate that the former Hollywood couple have reunited once again. The former lovers were recently seen at a Halloween party in Los Angeles as well as in Roosevelt Hotel, partying once again in September.

"He took her and grabbed her and started dancing with her, basically throwing her around and she loved it," a source reportedly told Hollywood Life, "They were talking close and holding each other and she was laughing at everything he said, she was enamored and definitely was equally flirting with him and he was really trying to impress her," the source added.

Although it might be good news for the fans rooting for the couple, neither Dobrev nor Hough have confirmed or denied the rumors. The rumors remain a mystery which has been led sources to use the term "secret boyfriend" to refer to Dobrev's speculated new beau.

"Now, we can't say whether this is a legitimate 'boyfriend', a fling ... or just some random dude that our sources saw her with," a source told Celeb Dirty Laundry said, "According to her reps and everyone close to her, Nina Dobrev's new boyfriend is a mystery," the source added.

Dobrev's personal relationships have been in the spotlight lately especially when she dated her 'Vampire Diaries' co-star Ian Somerhalder. Some fans and news agencies are even still hoping that the two reunite, but reports say it is highly unlikely since Somerhalder is currently dating actress Nikki Reed.

The press are still waiting for Dobrev's official statement to finally confirm her new mysterious "secret boyfriend" if indeed she has one.
