Melanie Griffith has gushed about how proud she is of daughter Dakota Johnson, who stars in the much anticipated film, Fifty Shades of Grey,

"My beautiful child I am so thrilled for her She is amazing! proudmama gushingsilly veryprotective," her movie star mum wrote on Instagram on Wednesday.

Johnson told the magazine she is thinking about her dwindling anonymity.

"That's really scary because a very large part of me would be perfectly happy living on a ranch in Colorado and having babies and chickens and horses, which I will do anyway," she said.

"I've ever experienced anything like this; I don't think anyone has. It's terrifying and it's exciting."
