IF only she could turn back time now.

Cher has apologised on social media for confusing Tony Abbott with former UKIP leader Nigel Farage.

The US singer posted a photograph of Mr Abbott and newly appointed Foreign Secretary Boris Johnson with the caption: “IN THE US…THEY’D BE TWIDDLE DUMB & TWIDDLE DUMBER?? IN UK…THEY’RE TWIDDLE TOSSER & TWIDDLE WANKER??”

The music legend later tweeted she was a “twit” for confusing Mr Abbott, with Mr Farage.

Mr Farage and Mr Johnson both backed the Vote to Leave campaign before Britain’s referendum, where a majority voted to leave the European Union.

“Sorry thought I hit photo of Boris and Nigel, IM (sic) A TWIT”, she posted.

Lots of followers brought the error to her attention.

For the record, this is Farage, the man Cher thought she was referring to in the photograph above.
