Madonna gets into the groove
Madonna has followed Katy Perry's lead in appearing nude in an attempt to get Americans to vote for the next US President on Nov 8.
In the 58-year-old US pop star's Instagram post, the carefully-cropped picture shows the bottom of her nose to the top of her breasts and some accessories.
She captioned the picture as: "I'm voting naked with Katy Perry!! Vote for (Democratic candidate) Hillary (Clinton). She's the Best we got!"
US singer Perry recently used her body as "click bait" when she appears to be nude in a parody collaboration between comedy video website Funny or Die and Rock the Vote - a non-profit organisation aimed at encouraging young Americans to vote.
The clip, released on YouTube on Tuesday, shows Perry heading to the polls in her pyjamas.
She says: "Yup, I've briefly scanned the Constitution, and nowhere does it say you can't just roll out of bed and come to the polls in whatever state you woke up in."
"I sleep naked," she declares and takes off the pyjamas.
