Actress Dakota Johnson had to teach her mum Melanie Griffith about the dangers of Twitter when the Working Girl star started to post her inner-most thoughts on the microblogging site.
The young star admits her famous mum had no concept of how popular tweeting was when she first started using Twitter.com - and she had to intervene in a bid to stop Griffith from making a fool of herself and sparking gossip items in the tabloids.
Johnson explains, "She started out just tweeting at herself... and she would also tweet at people that she knew not realising that the whole world can be privy to this information.
"She's like, '@RickyMartin, hey handsome, how ya doin?' and he didn't respond."
