Jesus take the wheel! Carrie Underwood isn't letting Sound of Music Live! critics get her down. The country singer has slammed "mean people" via Twitter on the very same day the film's original star, Kym Karath, bashed Underwood for her acting chops. Karath played Greti von Trapp in the 1965 musical film The Sound of Music. Watch video of her performances here.

"Plain and simple: Mean people need Jesus," 30-year-old Underwood wrote via Twitter on Friday, Dec. 6. "They will be in my prayers tonight…1 Peter 2:1-25." The Bible scripture Underwood cites states to "rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind."

Underwood responded to "mean people" just hours after the internet exploded with some harsh words about the show. Karath was one of many to comment about the live event, and slammed the singer for landing the role of Julie Andrews' Maria von Trapp. At the time, Karath was watching the three-hour program with former costars Charmian Carr (Liesl von Trapp) and Angela Cartwright (Brigitta von Trapp.)

"Mystified & disappointed so far by SOM special," Karath tweeted during the live performance on Thursday. "So far only happy with Stephen Moyer." (True Blood star Moyer played Christopher Plummer's Captain von Trapp.) "Must admit some scenes are actually painful to watch."

She added: "Love Carrie Underwood but this role is just not right for her. She is lovely her voice is beautiful but acting is wrong."

Despite snarky tweets from viewers, Underwood shared her excitement for how well the production went shortly after the curtain closed. "Glory to God tonight…I couldn't be more proud," she tweeted. "What a tough thing to pull off and we did it! I am so blessed!!!" Sound of Music Live! ultimately pulled in 18.47 million viewers for NBC.
