American singer Miley Cyrus is facing a lawsuit alleging that she and other songwriters copied Filipino-American singer Bruno Mars' song when they wrote her hit song "Flowers," American magazine Rolling Stone said in a report on Tuesday.

Based on the lawsuit obtained by the magazine filed on Monday in Los Angeles federal court, a company called Tempo Music Investments claimed “Flowers” includes unauthorized “exploitation” of several elements of Mars’ 2013 song “When I Was Your Man.”

The suit also names Sony Music Publishing, Apple, Target, Walmart, and several other companies as defendants accused of distributing “Flowers,” the report added.

The report states that Tempo Music said that it owns a portion of U.S. copyrights to “When I Was Your Man” after acquiring it from Philip Lawrence, who co-wrote the song along with Mars, Ari Levine, and Andrew Wyatt.

Mars is not named as a plaintiff in the suit, it added.

“Any fan of Bruno Mars’ ‘When I Was Your Man’ knows that Miley Cyrus’ ‘Flowers’ did not achieve all of that success on its own. ‘Flowers’ duplicates numerous melodic, harmonic, and lyrical elements of ‘When I Was Your Man,’ including the melodic pitch design and sequence of the verse, the connecting bass-line, certain bars of the chorus, certain theatrical music elements, lyric elements, and specific chord progressions,” the lawsuit obtained by Rolling Stone claimed.

“It is undeniable based on the combination and number of similarities between the two recordings that ‘Flowers’ would not exist without ‘When I Was Your Man,’” the complaint, which names Cyrus’ fellow songwriters Gregory Hein and Michael Pollack as co-defendants, continued. “With ‘Flowers,’ Cyrus, Hein, and Pollack have created a derivative work of ‘When I Was Your Man’ without authorization.”

It added that Tempo Music is seeking damages in an amount to be determined at trial; it is also demanding a court order prohibiting Cyrus and the other defendants from reproducing, distributing, or publicly performing “Flowers.”

As of writing, Rolling Stone said reps for Cyrus did not immediately respond to their request for comment.

"Flowers" was released on January 13, the birthday of her ex-partner Liam Hemsworth.

Cyrus recently won Best Pop Solo Performance and Record of the Year with the song.
