Watch Out Nina Dobrev! DWTS' Derek Hough Compliments Nicole Scherzinger On New Music

Dancing With The Stars professional Derek Hough has taken to his Twitter account to praise X Factor judge Nicole Scherzinger on her new music.

The talented dancer, who is rumoured to be dating The Vampire Diaries star Nina Dobrev, decided to shower praise on Nicole when she tweeted about her new music on her official page of the social networking site.

Having retweeted Nicole's message: "Beautiful new song 2 quench ur classical appetites! Check out my collaboration with @david_garrett 'Io Ti Penso Amore'", Derek who won DWTS in 2010 with Nicole, added:

"Wow. Ive always said you should do a classical album . Your voice has no limits."

However, Derek hasn't only been dishing out the praise to Nicole as he also had a few kind words to say about his sister Julianne who replaced Len Goodman on the latest episode of Dancing With The Stars.

As the show got underway and the celebrities began to show off the moves they had learned, Julianne was on hand to give feedback, even to Derek who has been partnered up with Glee's Amber Riley this season.

Gushing about Juliane and her role as a judge on the show, Derek told E! News that he was proud of his sister.

Derek commented: "Julianne and I are so honest with each other I understand what she meant tonight. She said she kind of wanted there to be something she could say [to critique the performance] so that she wouldn't seem biased.

"But I know that if she wanted to she would have taken much pleasure in doing that. It was great she did a really great job and I was really proud of her."

Meanwhile, as Julianne made her debut as a judge on the show, it was the end of the line for actress Valerie Harper who was eliminated from the show.

Speaking about her exit alongside her professional dance partner Tristan MacManus, Valerie said: "It has been absolutely wonderful - completely unique, like nothing else in the world that you would ever do and it was an opportunity for me to carry a message to folks, not just with cancer.

"Whatever challenge, [just] keep on, keeping on."

Tristan added: "I feel like maybe my life is a little bit better since I met Valerie Harper."
