Is Nina Dobrev Dating Derek Hough After Ian Somerhalder Split?

Is Nina Dobrev dating Julianne Hough’s brother, Derek Hough? According to one "insider," the pair are getting pretty cozy.

In Cosmopolitan’s September issue, Dobrev tells the magazine that “people aren’t defined by their relationships.” But that doesn’t mean her love life isn’t a hot topic for fans. After breaking up with her “Vampire Diaries” co-star Ian Somerhalder in May, the 24-year-old has taken advantage of her single status – rocking hot outfits to parties and events, posing in sexy lingerie and vacationing with friends.

Although the actress told Us Weekly earlier this month that she’s “in no rush” to jump into her next relationship, Star Magazine is reporting that Dobrev’s good friend Julianne Hough has hooked her up with her “Dancing With The Stars” pro brother, Derek Hough. So, what’s true and what’s false?

Star claims that Hough didn’t want to “see [Nina] with a loser,” and since she’s “super picky” about her brother’s love life, she decided to set them up.

A rep for the “Vampire Diaries” starlet told Gossip Cop that any story of Julianne Hough hooking Dobrev up with her brother is “not true.” Instead, the rep insists that Nina and Derek are “just friends.”

"I've been a relationship girl and I've been in long-term relationships my whole life until this point, so I think I'm looking forward to spending some time with myself and finding myself again," Dobrev told Us. "I'm just discovering different sides of me and growing, and then I'll figure out what I like in a man when I see it."

Dobrev and Derek Hough have been friends for quite some time. In January, when the actress celebrated her 24th birthday at Dior’s Hollywood Glamour Dinner, the dancing pro was photographed with her and then-boyfriend Somerhalder.

Since “The Vampire Diaries” couple broke off their three-year romance, Hough and Dobrev have been caught hanging in group settings. In June the Hough siblings went on a tropical vacation with Dobrev, “That 70s Show” star Topher Grace and others. In early August Dobrev took a break from filming season five of “The Vampire Diaries” to dance at Chicago’s Lollapalooza with Derek and some famous friends.

Star’s insider said the pair seemed “really into each other” at Lollapalooza. Do you think they are a couple, or just friends? Let us know your thoughts in the comments section.
