Madonna endorsed President Obama at her concert on Monday night in Washington D.C., which involved her stripping down to reveal the president's name written on her body.
Madonna told the crowd: “You all better vote for f*cking Obama okay," reports TheHill.com.
Later in the show, Madonna took off her shirt and pulled down her pants to show “OBAMA” written in all capital letters across her lower back.
She added: “When Obama is in the White House for a second term I'll take it all off."
She then sang a slow version of 'Like a Virgin' while rolling around on a piano. Later in the show she said: “I get a little worked up about some subjects.”
