After Avril Lavigne's recent divorce from Chad Kroeger, the singer's troubles seem to be piling up as she is reportedly feuding with her "Charming" co-star Demi Lovato.

In a report by Celebrity Dirty Laundry, Avril Lavigne allegedly does not like the diva attitude of her co-star in the Disney film "Charming."

"It has been a nightmare. They are both so strong willed and outspoken that what starts off as a suggestion from either Demi or Avril turns into a full blown argument," an insider told Life & Style magazine as shared by Celebrity Dirty Laundry.

"Demi is an executive producer on the score for the film, and she is the one who recommended Avril for the role of Snow White. But now they can't stand each other, there is a lot of eye-rolling and name calling," the insider added further.

Even Demi Lovato has been allegedly dragged into the controversy. Reportedly, the Canadian pop-rock singer does not want to take orders from the "Really Don't Care" hitmaker.

Wilmer Valderrama's girlfriend, who is also the executive producer of the animated Disney movie "Charming," is said to be a "tough pill to swallow" as Avril Lavigne is not the first person she had a row with in Hollywood.

Meanwhile, Hollywood Reporter said that Demi Lovato is set to voice the female lead role, Lenore, while Chad Kroeger's ex-wife will be the voice of Snow White.

They will be joined by Ashley Tisdale and Chinese star G.E.M., who will play as Sleeping Beauty.

Before Avril Lavigne landed the role of Snow White in the movie "Charming," she first dealt with her divorce from Chad Kroeger, whom she married in 2013.

The former couple confirmed that they are pulling the plug off in their relationship through an Instagram post that claimed they are not only separating with regard to their personal life but as welll as professional engagements.

Avril Lavigne is now rumored to be dating close friend Ryan Cabrera.
