Carrie Underwood may the sweetheart of country music, but her decision to use her singing chops for the world of musical theater may have cost her some fans.

According to the 30-year-old "Blown Away" singer, her upcoming performance in a live television debut of the musical "The Sound of Music," portraying the lead role of Maria Rainer made famous by actress Julie Andrews in the 1965 film, has resulted in her receiving a barrage of negative messages on social media.

"I get hate tweets and stuff like, 'You're not Julie Andrews!'" Underwood told Entertainment Weekly via the Daily Mail.

Despite receiving criticism for starring in the popular musical, which tells the story of a woman who cares for windowed Naval officer's several Von Trapp children, Underwood said she understands why fans are so hesitant to see her take on the leading role. "I know I'm not Julie," said Underwood, adding, "Nobody is and I would never pretend that I was. I know my place."

While the creators behind "The Sound of Music" remake have already shared their thoughts on the casting drama, music producer Neil Meron saying, "Carrie is Maria," fans appear to still be undecided about the casting decision. As of Friday morning, hate tweets regarding Underwood's upcoming role in the musical were still flooding twitter feeds.

"Whoever green lighted the Sound of Music with Carrie Underwood should be shot," tweeted user @jonco27 Friday. "Wait a sec, Carrie Underwood and Sound of Music?!? Thanks for ruining my childhood lol," tweeted user @Peter_Shayne Friday.

"The Sound of Music" live TV special airs on NBC on Dec. 5th at 8 p.m. ET.
