In Touch reports on which cell phone covers are popular with which celebrities. Heidi Klum, Seal, Avril Lavigne, Usher and Courtney Love are among those who use mini-stuffed-animal covers; Oinky the Pig, Funky the Monkey and Cuddles the Dog, all available from funfriends.com. Cameron Diaz, Gwen Stefani and Big Boi of OutKast favor pink excess with Hello Kitty cell phone covers. Jessica Simpson, Lindsay Lohan, Hilary Duff and Paris Hilton use Bling Ring, encrusted with rhinestones by Sarah Gold. None of the stars named could be reached for comment on the notion that the most sophisticated-looking cell phones are the ones that people use without any Hello Kitty, gaudy rhinestone or Oinky the Pig cover.
