It's Ruby, Ruby Megan Henson, Charlotte Church announced yesterday. The baby, whose existence was first guessed when the singer elected to spend her 21st birthday meekly having tea and cake with her nan, was born at her home in Wales on Thursday night, "and weighed in at 6lb 12oz, exactly the same weight that Charlotte was when she was born", according to her webmaster who passed on the joyful news to the world. They are said to have fancied the name Ava, but it was nicked by Myleene Klass, whose baby was born last month. Mean spirited bloggers have already pointed out that the proud father, rugby player Gavin Henson, was around to attend the birth because he wasn't picked to join the Wales squad for the world cup, after an achilles tendon injury. However one yesterday suggested a useful supporting role for him: "If there are any paparazzi outside your house, get Gavin to chuck dirty nappies at them, or kick 'em over the fence. Good training for the new season."

It could easily have become a fish called Wanda. Or even a shark called Prince Albert II of Monaco, Lord Linley, Camilla du Borbone, Princess Serge of Yugoslavia, or Salah al Fayed - brother of Mohamed - since the prince was hosting the event in the aquarium down the road from his palace, they were all guests, and any one of them might well have had have had a spare £250,000 in pocket or evening bag to christen the new species. The Blue Auction, raising funds for marine conservation, conducted by Christie's in Monaco, was for the right to name new marine creatures recently discovered by Conservation International in Indonesia. The evening raised more than £1m, but the top bid was for hemiscyllium cenrawasih, a new species of walking shark - which can swim but prefers crawling on its pectoral fins. But alas, neither the bidder nor the new name has so far been revealed. The shark should probably just play safe, and address any rich person who swims past as "mummy".

Thomas Heatherwick's new design looks remarkably like a sea creature that could have turned up in the Blue Auction rather than a trade pavilion. It's a sort of giant sea-urchin blob, covered with spines which shiver and change colour, and it has just won his studio the prize to design the UK pavilion for Shanghai Expo in 2010. Lord Jones of Birmingham, who chaired the jury, said they were "energised by the uniqueness of the concept" which would provide "a sensory experience for visitors" - but frankly it's not at all clear how they get in, it doesn't seem to have anything as vulgar as a door.
