Cher has never planned ''a single thing'' in her entire life.

The 72-year-old icon recently starred in 'Mamma Mia! Here We Go Again' and is set to release 'Dancing Queen' - an album that features songs recorded by the Swedish pop group Abba - later this month, but Cher has insisted it's not something she's carefully mapped out.

She said: ''I don't account for things that way. I just do them. I've never planned a single thing in my entire life. It's like this ABBA album. I did the film. I didn't ask to do it. My friend Ronnie Meyer called and said, 'You're doing 'Mamma Mia', and hung up.''

Asked why she didn't refuse, Cher told the New York Times newspaper: ''Ronnie used to be my agent. He ran Universal, and he's my dear friend. So when he hung up, I thought, 'Damn!' Then I thought, 'Well, it's going to take five minutes, and no one will even know I'm there.'''

Despite the movie being one of the biggest releases of 2018, Cher still hasn't seen the final cut.

She shared: ''I haven't seen it. But can I tell you, I don't remember doing anything memorable, except singing 'Fernando'.

''Afterward, when Jen [her assistant] and I were packing to go home, I said, 'You know what might be fun?' This is how I get myself into all kinds of trouble. 'It might be fun to do an ABBA album.'

''The songs are easy to sing, but they're complicated, too. Some of them are hard as hell, which is why I was in the studio again tonight.''
