Cher's first kiss was with an ''idiot''.

The 70-year-old singer - who was previously married to the late Sonny Bono and Gregg Allman - admits the first time she got close to a guy wasn't ''that good'' but she instantly recognised the ''possibilities'' that came with kissing.

Asked if she remembers her first kiss, she smiled and said: ''He was an idiot. My mother had a friend and she had a son and he took me on a hayride and he kissed me and it wasn't that good but I thought, 'This thing has possibilities.'''

Next year, the 'If I Could Turn Back Time' singer will embark on a concert series called 'Classic Cher', with residencies in Las Vegas and Washington D.C., and the legendary entertainer has promised those who attend the shows won't be disappointed.

She told 'Extra': I'm trying to give people something that if they come and have been a fan they will get all the things that they loved.''

And Cher has also been hard at work on a Broadway production based on her own life, and has revealed the project will feature three versions of herself in different eras and ages.

However, they won't be telling a typical story as the three Chers will interact with one another.

She explained: ''The idea of having three Chers, the young, the medium and the old, sometimes one talks to another and says, 'Don't sweat the small stuff, because I'm over here you're gonna go through more...' And they'll sing together at some points.''

Meanwhile, despite her own years of fame, the 'Believe' hitmaker admits she still gets starstruck.

She said: ''It's been a while but I've been starstruck many times, like when I met Meryl [Streep]. then she came up and grabbed me and said, 'I'm so glad you're here.' ''
