Nina Dobrev and her Vampire Diaries costar, Ian Somerhalder, sadly broke up earlier this year. But the pretty actress has rebounded quite well, as she's now dating Dancing With The Stars pro-dancer Derek Hough.

The new couple began dating in August, according to sources for Us Weekly magazinebut apparently, Dobrev and Hough were good friends long before that, even while the Bulgarian beauty was dating Somerhalder.

Dobrev has been best friends with Hough's sister, Julianne, for some time and the three often hung out together. "[Nina] was hanging a lot with Derek's sister Julianne. Then she fell for him," a source told Us. Additionally, another insider is claiming that it is getting quite serious between Dobrev and Hough, even though they have only been dating for a few weeks, E! News reported.

Fueling rumors that she and Hough were an item, Dobrev posted a series of messages and Instagram photos when her new boyfriend won the Emmy for Outstanding Choreography on Sunday night.

"@Derekhough !!!!!!!! #EMMYWINNER I cant express in 140 characters how unbelievably excited+incredibly proud I am of you. You deserve this," she wrote captioning a photo of Hough holding his award. She later added a photo of her new beau and his sister Julianne with the caption, "I wish I wasnt filming so I could have been there to celebrate w/u guys!"

Further proof of a Dobrev-Hough romantic paring came when a fan posted a video of the two as they held hands during a performance at the Los Angeles Roosevelt Hotel a couple of weeks ago.

Meanwhile, Dobrev still keeps a friendly relationship with ex Somerhalder as the two reunited to begin shooting for the new season of The Vampire Diaries.
