Alanis Morissette knows how to put a twist on things and she's got another supastar loving her "genius" skills.
Alanis 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-colored cake read, 'Alanis, you're a genius. Love, Fergie.' "
The bakery delivered the cake to Alanis last Friday.
