Al Pacino hasn't done his own grocery shopping for 50 years.

The 74-year-old screen legend - who has a grown-up daughter, Julie Marie, with an ex-partner and 14-year-old twins Anton and Olivia with former girlfriend Beverly D'Angelo - admits he hasn't been able to lead a normal life since finding fame several decades ago.

He said: ''I haven't been in a grocery store or ridden a subway in 50 years.''

The 'Godfather' star insists he doesn't mind being recognised when he is out and about, though his kids find it harder to deal with.

He said: ''I don't mind [fame] but my kids have a difficult time going out with me publicly.

''I'm fine not having anonymity, I've sort of learnt how to live with it.''

The 'Danny Collins' star will support his children if they decide to follow in his footsteps because he thinks they are already showing signs of talent.

Asked if he would encourage his kids into showbiz, he told Britain's HELLO! magazine: ''If there is talent - which there is - I will. Who else is going to hire me when I get old?

''My youngest daughter made a video the other day - just like that - put it together, edited, did the whole thing. Amazing.''
