Jessica Simpson is amazed by her fashion mistakes.

The singer-and-actress is currently having a huge clear-out of her wardrobe and is astonished by some of the disasters she has discovered at the back of her closet.

She tweeted: "Cleaning out my closets...20 boxes of NO's so far. Really? I bought this? My lord!! Hahaha. (sic)"

Meanwhile, the 29-year-old star drank distilled cow urine for her new TV show 'The Price of Beauty'.

Previews for the series - which airs in the US from later this month - show the 'Dukes Of Hazzard' actress being offered the "detoxifying" drink while examining beauty secrets in India.

When she sees the label on the bottle, the horrified star exclaims: "Like pee? Cow urine?"

Other beauty rituals Jessica tries out for the show include having fish nibble her feet in Japan to get rid of dead skin, a painful back massage, donning geisha make-up to try the local Tea Tray Dance in Morocco and wearing a shining samba outfit while balancing a tray of candles on her head in Brazil.
