The Material Girl singer took to Instagram on Thursday (01Sep16) to share a picture of Donald Trump Jr. and Eric Trump holding the big cat and in an accompanying message the 58-year-old criticised the brothers, while officially endorsing their father's presidential rival Hillary Clinton.

She wrote: "How Big of (a) P**sy Do you have to BE to kill this Noble Animal for sport? Just ask Donald Trump Jr and his brother Eric. One more reason to vote for Hilary!"

Madonna is not the only celebrity to endorse Clinton - Cher, Kerry Washington, Debra Messing, Justin Timberlake, and Paul MCCartney have all thrown their support behind the former Secretary of State.
