The 'Living for Love' hitmaker - who has four children, Lourdes, 18, Rocco, 14, David, nine and Mercy, eight - would rather advise her kids than give them rules.
Speaking about her eldest daughter, she said: 'I'm not a fan of taking drugs, but I'm not gonna tell my daughter not to do things. I'm just telling her to be careful.'
'[I tell her] never take a drink that you haven't seen somebody pour in front of you. Don't mix alcohol. Your basics, like be safe, do everything in moderation. That's it. That's all I can do.'
The 56-year-old star also believes it is important not to be 'judgemental' of her children because she feels it is discouraging for them.
When asked if she talks about sex with her children, she told Access Hollywood: 'It's just a fact of life isn't it? Somehow, it's gonna happen sometime. It happened to you, so it's gonna happen to [Lourdes]
'All you can do is [stress] safe sex. Have discussions about it and encourage her to be open with you about it and not judgmental. Because then they won't feel like they can come to you and talk to you - ask you for your advice and stuff.''
