Demi Lovato Rooting for Rob Kardashian on ‘Dancing With the Stars’

If you're a big Demi Lovato fan, chances are that you already know the singer is good friends with the Kardashian family. She was recently photographed at the 2011 Do Something Awards with Kim Kardashian, and she even attended the TV personality's wedding to Kris Humphries. Now, Lovato is showing support for another Kardashian, Kim's little brother Rob, who is currently competing on 'Dancing With the Stars.'

Lovato took to Twitter to help gain support for Rob Kardashian from her group of loyal fans, known as Lovatics. The 'Skyscraper' songstress wrote, "Everyone vote for my very good friend @RobKardashian tonight on Dancing With the Stars!!!! #VOTE4ROB." Lovato was also retweeting Rob's Twitter posts urging people to vote for him. With more than 4 million followers on Twitter, we're sure Rob was cranking in the votes.

In the past, Lovato and the lone Kardashian boy have gotten mildly flirtatious on Twitter (via Hollywire). In the past, Rob Kardashian has written to Lovato, retweeting at Lovato, "You always get TT worldwide! YOUR FANS LOVE YOU!!! : ) RT @ddlovato Wow another TT worldwide?!!!? I LOVE you guys!!!!!" Lovato responded to the retweet, writing, "@RobKardashian I know my fans are the best!! You're alright too : P."

Although Demi Lovato and her fans are supporting Rob, the Kardashian sibling has some stiff competition, dancing against people like Kristin Cavallari, Carson Kressley, Nancy Grace, Chaz Bono and David Arquette, to name a few. With many more weeks of competition left, Kardashian's fate is still fairly unknown.
