Miley Cyrus found an ally on her So Undercover co-star Kelly Oubourne, as the latter defends Miley from allegations that she is a bad influence on Osbourne. The allegations stemmed from reports that Kelly's mother Sharon pegged Miley as a bad influence on her daughter.

"Actually it's the other way around Miley has us all on a health kick. Gym/early nights. There really scraping the barrel on that one!," wrote the reality star on Twitter.

"This really makes me mad. Miley is one of the most hard working respectful women I have ever worked with I am learning a lot from her! Miley and I have become really close I'm sick of all the haters judging her she[made] one mistake and trust me she has learned her lesson!"

Recently, Miley Cyrus figured in a salvia bong video uploaded in the Internet. The video shows Miley under the influence of salvia, a known hallucinogenic. It solicited criticisms for the former Hanna Montana star, with some sectors calling it irresponsible since many of Miley's fans are young adults.

Cyrus was not doing anything illegal by consuming salvia, since at the time the video was recorded she was already of legal age, and salvia can be legally obtained in the state of California.

Kelly Osbourne and Miley Cyrus stars in the comedy action film So Undercover. Osbourne tweeted a photograph of her and Miley eating cupcakes on the set, writing "This is how im a bad I influence on Miley I force her to eat cupcakes so I don't feel so bad about eating one!"
