Model Sophie Dahl is expecting a baby with her musician husband Jamie Cullum, a spokesman for the couple confirmed.

David LaChapelle made his name with mash-ups of trashy glitz, Old Masters and videos of Angelina Jolie, Courtney Love and Madonna. But on the eve of his first seriously political show in the UK, he tells Fiona Sturges that he has put commercialism behind him

If you ask me, now the election has been called, it is time to throw my hat into the ring, which is harder than it looks, particularly as I don't have a hat, or a ring.

Did they consider a fig leaf? The Victorians made one for Michelangelo's David, and I'm sure someone could have come up with a version to protect the modesty of both Cranach's Venus and the delicate sensibilities of travellers on London's Tube trains. Two days ago, Transport for London suddenly reprieved the goddess of love, who had earlier been banned from advertising the Royal Academy's forthcoming exhibition of the work of the 16th-century German artist.
