Alanis Morissette's butt cake

Alanis Morissette has been sent a butt-shaped cake by Fergie.The Canadian singer has recorded a moody, down-beat version of the Black Eyed Peas' hit 'My Humps' and the video - in which she dresses up as Fergie and shakes her 'hump' before beating up gangster-style men - has become a You Tube sensation.Fergie thinks the song and promo are hilarious and wanted to show Alanis her appreciation with the rude calorific treat.A source said: "Fergie thought the video was brilliant. She sent Alanis a cake in the shape of a derriere."Rosa Leung, 52, of Los Angeles bakery Exotic Cakes, who created the unusual treat, said: "A note on the flesh-coloured cake read, 'Alanis, you're a genius. Love, Fergie.' "The bakery delivered the cake to Alanis last Friday (06.04.07).
