Not so sweet: Sadie Frost's 11-year-old daughter Iris shocks with a very rude 'love hearts' dress at Vivienne Westwood show

At first glance it appears to be a sweet dress - very age-appropriate for an 11-year-old.

But on closer inspection, one wonders what Sadie Frost was thinking when she allowed her daughter Iris to leave the house wearing an outfit that declares 'drop dead', 'drink poison', 'eat sh*t' and a plethora of even more X-rated messages.

Iris, Frost's child with Jude Law, sat front row wither her mother at the Vivienne Westwood show at London Fashion Week on Sunday.

Hardly child-friendly: Iris' love hearts dress had some very rude messages

The celebrity offspring teamed her dress with white lace tights and a ripped blazer as she sat snapping pictures of the models on her iPhone.

Sadie wore a bright orange cardigan with a lace blouse for the presentation and chatted to her daughter and admired her pictures throughout the show.

It is unknown if the 46-year-old mother-of-four was actually aware of the rude message on the love hearts dress, and a spokesperson is yet to respond to Mail Online's request for comment.

In 2002 Iris, then aged two, was rushed to hospital after swallowing part of an ecstasy tablet at a children's birthday party.

The pill had been left on the floor of Soho House, when the party was held.

Also bringing their daughter along was Heston Blumenthal, who posed before the catwalk show with his teenager Jessica.

Unlike Sadie, Heston was unable to blag another seat in the VIP section on the front row, so was forced to sit without Jessica.

Other celebrities in attendance were Jo Wood, in a plunging red gown, Gizzi Erskine, Rita Ora and Gabriella Cilmi.

Somewhat bizarrely, the designer admitted at the Red Label show that she does not like some of the clothes in her collections.

Dame Westwood said the rise of disposable fashion means people look too similar. Speaking before the show, she said: 'In history people dressed much better than we do today. If you saw Queen Elizabeth it would be amazing, she came from another planet. She was so attractive in what she was wearing. People have never looked so ugly as they do today regarding their dress.

'We are so conformist, nobody is thinking. We are all sucking up stuff, we have been trained to be consumers and we are all consuming far too much.

'I'm a fashion designer and people think what do I know but I'm talking about all this disposable crap.

'So I'm saying buy less, choose well, make it last. Everybody looks like clones and the only people you notice are my age. I don't notice anybody unless they look great, and every now and again they do, and they are usually 70.'

Dame Vivienne said delegating some of her designs means sometimes she ends up being unhappy with how they look.
