Mexican authorities are investigating Miley Cyrus after one of her dancers whipped the singer's fake buttocks with the country’s flag during an Independence Day concert Tuesday night, media reports said Wednesday. The 21-year-old has previously made headlines for rumors of drug overdose and her sexually suggestive dance performances.

A Mexican state legislature reportedly requested the country’s federal government to fine the “Wrecking Ball” singer for desecrating the flag. The singer could be fined $1,200 for her actions and could be detained for 36 hours, a spokesperson for the interior ministry told Agence France-Presse, or AFP. Cyrus was performing in Monterrey, capital city of the northern state of Nuevo Leon. A video from the concert, which showed Cyrus’ dancer whipping her mock backside with a small flag, reportedly surfaced on local media.

"They are hitting her with the flag, or cleaning her backside. It's a lack of respect," Nuevo Leon lawmaker Francisco Trevino said, according to AFP. "The interior ministry must sanction the singer Miley Cyrus for desecrating the flag," he said, adding that authorities should keep a check on her future performances in the country.

A spokesman for the interior ministry also told AFP that "the company that brought her here would be sanctioned, not her" because it was the responsibility of the organizers to monitor the concert.

Cyrus also gulped some water and spit at her fans, an action that initially brought screams of joy but later annoyed the fans, according to a local report.

According to reports, in 2008, Mexican pop star Paulina Rubio was fined $4,000 for appearing in a Spanish magazine with the Mexican flag wrapped around her naked body.
