Lady Gaga and Madonna Charged With Breaking Russian Immigration Laws? Gaga Fights Back, 'Why Didn't You Arrest Me When You Had the Chance?'

Lady Gaga and Madonna could reportedly face charges after Russian officials claimed the megastars did not obtain the correct visas to perform in their country.

According to the Gaurdian, Madonna and Gaga, who both performed separately in Russia in 2012, are now accused of entering the country using cultural-exchange visas that do not allow holders to "engage in any commercial activity" while abroad.

The investigation was prompted by controversial Russian politician Vitaly Milonov; known best for authoring St. Petersburg's anti-gay law that bans LGBT propaganda from being spread.

Milonov is asking that Russia's foreign ministry or federal migration service press charges against the singers for their actions.

This is not the first time Milonov has targeted the pair. He tried, without success, to slam them with legal charges for speaking in favor of gay rights during their Russian performances. At the time, he accused them of "promoting sodomy, lesbianism, bisexuality and transgenderism among minors."

Following the news, Gaga, who recently returned from a social media break, took the opportunity to fight back against the charges and Russia's current poor treatment of LGBT youth.

"Sending bravery to LGBTs in Russia. The rise in government abuse is archaic. Hosing teenagers with pepper spray? Beatings? Mother Russia?" she tweeted, referring to recent and highly publicized events.

"The Russian government is criminal. Oppression will be met with revolution," she continued. "Russian LGBTs you are not alone. We will fight for your freedom... Why didn't you arrest me when you had the chance Russia? Because you didn't want to answer to the world?"

Madonna has yet to respond to the accusations.

Concert promoters in Russia worry that if the singers are charged, it will deter other acts, and tourists, from visiting the country.
