Pixie Geldof organised a ''guess the poo'' game at her sister Peaches Geldof's baby shower.
The 21-year-old singer - the youngest daughter of Live Aid co-founder Bob Geldof and late TV presenter Paula Yates - passed around soggy nappies filled with melted chocolate, and the guests had to sniff the fake faeces to try to work out which brand of chocolate it was.
