Cyrus gets flagged by Mexican officials

• Miley Cyrus act in Monterrey included a "spanking" with the Mexican Flag


• Nuevo Leon state legislator: "She brazenly made fun of our flag"


• He says Mexico's Interior Ministry has opened an investigation


• Tuesday, the day of the incident, was Mexico's Independence Day

(CNN) -- Miley Cyrus came to Mexico "like a wrecking ball" -- to quote her hit song -- offending fans at Monterrey concert and prompting a federal investigation.

This happened Tuesday in Monterrey, during the first of four scheduled "Bangerz Tour 2014" gigs in Mexico:

As Cyrus was "twerking" in the middle of a song, one of the two dancers contorting beside her used a Mexican flag to spank the oversized, false buttocks she was wearing.

Adding insult to injury: Tuesday was Mexico's Independence Day.

There was much excitement when Miley Cyrus launched her "Bangerz" tour in Vancouver, British Columbia, in February, but since then the controversial singer has been beset by woes including ending up in the hospital with "a severe allergic reaction to antibiotics." Here are a few other issues that have cropped up along the way.

Tragedy struck in early April with the death of the singer's favorite pooch, Floyd. Cyrus tweeted to her Boston fans in advance of her concert there that she was "beyond miserable." The gift of a new dog from her mother apparently did little to console her, as Cyrus later tweeted that she gave the new dog away to a friend.

Some parents were reportedly less than thrilled with the singer's provocative antics during her concerts.

Katy Perry and Cyrus got in some smooching action during the latter's Los Angeles concert in February. Cyrus tweeted the lip lock, though the pair later got into a beef about the smooch when Perry questioned Cyrus' tongue hygiene during a radio interview in March. They later made up -- via Twitter, of course.

In April 2014, a "Bangerz" tour bus caught fire, according to Cyrus' younger sister, Noah, who chronicled the incident on Twitter.

In April the singer was doing her thing on stage when a fight broke out between fans at a show in Detroit. Cyrus reportedly took time out to record the two women fighting for her Instagram account and can be heard yelling "Catfight!"

On April 15, Cyrus was hospitalized for a "severe" allergic reaction to antibiotics reportedly taken for a bout with the flu and had to cancel some dates. "Kansas I promise Im as (heartbroken) as you are," the singer wrote. "I wanted so badly 2 b there 2night. Not being with yall makes me feel s**ttier than I already do."

Mexican law is very stern on the subject of respecting the flag, the Mexican seal and national anthem: Any action "that implies contempt or lack of respect to the Homeland Symbols will be punished according to its severity and the condition of the offender."

The act of disrespecting a Mexican symbol carries a fine up to about $1,200 and three days in jail, and that's if it doesn't happen during the commission of a felony.

There's been no word about putting the international pop star in the slammer, but lawmakers in Nuevo Leon state voted unanimously Wednesday to condemn the incident.

Speaking to CNN, state Rep. Francisco Treviño said the Mexican Interior Ministry has opened an investigation at the request of the state legislature.

"I felt truly offended and annoyed by the fact that a foreign artist feels like she can come here and make fun of and mock our national flag on Independence Day, September 16th. She brazenly made fun of our flag," Treviño said.

Regardless of where the investigation goes, Treviño says, it seems the 21-year-old Cyrus and her concert organizers have gotten the message.

"It's important to notice that in her second concert Wednesday (also in Monterrey) she didn't desecrate the flag. There were several flags on display at the concert venue, but their use was appropriate. I hope this incident serves to get the message out that we Mexicans don't like it when our flag is made fun of," Treviño said.

It's not the first time the singer has been at odds with officials in Latin America. Regulators of public events in the Dominican Republic canceled her concert scheduled for September 13 in Santo Domingo on morality grounds.

Cyrus is scheduled to perform in Mexico City on Friday and Guadalajara on Sunday before "Bangerz" moves on to Chile and Argentina.
