When Adele voiced her support for Hillary Clinton on stage, she may have been unaware the Democrat presidential candidate was right there in the audience soaking up her praise in person on the eve of her 69th birthday.

Performing at a concert in Miami, the 28-year-old Grammy-winning singer broached the ever-present topic of the ferocious presidential election.

Adele said it was “hard work” to be an American at the moment and urged the crowd not to vote for Donald Trump and endorsed Ms Clinton instead.

“I’ve got to be honest with you, i’m really glad i’m not an American at the moment, it’s hard work,” Adele said at the concert on Tuesday.

“I wouldn’t know what to do, I mean I do know what to do - don't vote for him, that's all I'm saying.”

“I support Hillary Clinton 100 per cent, I do.”

“And for anyone else that wants to vote for him, I don't care, good for you, do whatever you want,” she added. “I'm just letting you know who I would vote for”.

Ms Clinton's campaign spokesman Nick Merrill told Sky News Adele said on stage that while she could not vote in next month's election, “what happens in America affects me too”.

In February, Adele told Mr Trump he did not have permission to use her songs at rallies after fans expressed anger at the fact he had appropriated her music for his campaign. The billionaire businessman had been using Adele’s widely popular hits "Rolling in the Deep" and "Skyfall" for his political rallies. “Adele has not given permission for her music to be used for any political campaigning,” her spokesman said at the time.

A representative for Ms Clinton and Adele did not immediately respond to request for comment.
