Madonna confused some Washington, D.C. fans by demanding that they support the "black Muslim in the White House" as she gave a profanity-riddled political endorsement of President Obama Monday night.

The singer brought her MDNA Tour to Washington, D.C. on Monday night, and added a bizarre dose of politics to the show.

"Y'all better vote for (expletive) Obama, OK? For better or for worse, all right? We have a black Muslim in the White House. Now that's some amazing (expletive)," she said. "It means there is hope in this country. And Obama is fighting for gay rights, so support the man, (expletive)."

The singer began the political detour during her MDNA concert stop in the nation's capital by remembering Abraham Lincoln and Martin Luther King Jr. as leaders who, she said, "fought for our freedom."

According to The Hill, the pop icon followed up that politically incorrect endorsement by taking off her shirt and pulling down her pants to reveal the name "OBAMA" written in all capital letters across her lower back.

"When Obama is in the White House for a second term I'll take it all off," she said, before launching into a sultry version of her 1984 hit "Like a Virgin."

Madonna also used body art to show her support for the president at a concert at Yankee Stadium earlier this month.
