Madonna unveiled a huge Obama temporary tattoo on her back during last night concert in New York.
Madonna, 54, made the unmissable statement during her MDNA Tour at New York’s Yankee Stadium.
Clad only in a back-baring bra and trousers she turned her muscly back on the audience, all the better to show off the writing.
Despite turning 54 last month there was no rest for Madonna during her high-kicking concert.
At one point the singer was joined on the stage by her bare-chested younger boyfriend Brahim Zaibat. She and the 24-year-old have been dating for two years.
Madonna has made her left-wing leanings increasingly clear in recent months, with her endorsement of President Barack Obama the latest in a long line of political statements.
The mother-of-four was branded a “moralizing slut” by Russia’s deputy prime minister after scrawling Pussy Riot on her back at her concert last month.
Madonna was making a statement about the jailing of the Russian punk band for an anti-Putin protest in a Moscow cathedral.
She then angered the Russians further by making a stand for gay rights at her St Petersburg concert
On that occasion she stomped on an Orthodox cross and asked fans to raise their hands to show pink armbands which had been distributed in support of gays and lesbians.
And in July the pop star was forced to make a public apology to France’s far-right nationalist leader Marine Le Pen after depicting the politician with a swastika across her forehead.
The leader of the National Front had said she would sue the pop queen for associating her with Adolf Hitler’s Nazis.
In an eccentric performance in front of 2,500 fans in Paris, Madonna said: “I know that I have made a certain Marine Le Pen very angry with me. It’s not my intention to make enemies.”
