The Miley Cyrus: Bangerz Tour special, which aired on NBC July 4 weekend, is being evaluated by the Federal Communications Commission in order to determine whether it violated any rules against indecency and profanity.
The FCC told Rolling Stone that the agency received a total of four complaints on the concert special.
The show was filmed earlier this year at her Barcelona and Lisbon tour stops, which also included behind-the-scenes footage.
The factors that likely drew the complaints were Cyrus' outfits including a skin-tight unitard and backup dancers dressed up as a giant blunt and cigarette lighters. The singer also performed a provocative dance with a man dressed as Abraham Lincoln. For one song, Cyrus also got comfortable in a giant bed with several men and women.
Rolling Stone reported the complaints verbatim.
"They aired a program called Miley Cyrus: Bangerz Tour," the first complaint began. "Now, during the summer evenings when the kids get to stay up late, why would they choose to air a highly controversial 'pop star' who freely advertises that her songs are all about sex and drugs, who wears costumes that would perhaps be more appropriate if she were dancing on a pole in some club somewhere?"
Another one read, "The live Miley Cyrus concert program was borderline pornographic in images and the lyrics to the songs. Open sexuality on a stage bed male/male female/female homosexuality. Very graphic and disturbing for a Sunday evening 9pm summertime broadcast. Please investigate this and prevent it from ever being shown again."
Both a spokesperson for NBC and a representative for Cyrus have declined to comment.
