Madonna, Katy Perry and Lady Gaga lead celebrity backlash to Donald Trump win

Madonna, Katy Perry and Lady Gaga have led a pop backlash against Donald Trump as celebrity supporters of Hillary Clinton reacted in dismay to the US presidential election result.

The American singers took to Twitter to bemoan the result and call for action to oppose the Republican's presidency, which will begin with his inauguration on January 20.

US singer and actress Cher warned the "world will never be the same" with Trump set to assume the Oval Office as his first official role in public affairs.

Harry Potter author JK Rowling, Lily Allen and Nigella Lawson were among notable British names expressing their disappointment and anger at the prospect of a Trump presidency.

Comedians Seth MacFarlane and Ricky Gervais also chimed in with witticisms while condemning the result.

US actress Lindsay Lohan attempted to generate a call on social media for a vote check.

British actor and US talk show host James Corden and US comedian Sarah Silverman both likened the result to Britain's surprise referendum result.

But amid the liberal backlash came cheers for Trump from the conservative side of the entertainment industry, led by actors Kirstie Alley, Stephen Baldwin and James Woods.

US comic and actor Roseanne Barr was another delighting in Trump's success.

Trump had also received public support during the campaign from Oscar-winning actor Jon Voight.
