Ryan Seacrest, Lady Gaga and Kim Kardashian are participating in the “Digital Sacrifice” campaign – all have gone dark on their Twitter and Facebook accounts “until million is raised.” Katie Perry lit up last night’s Victoria’s Secret Fashion Show, performing her hit song “Firework” – tonight, Perry will perform during the “Grammy Nominations Concert Live” which airs at 10/9 Central on CBS. Kate Gosselin is opening up about her children’s classroom problems to ”People Magazine.” Gosselin says two of her children, Colin and Alexis, are “struggling” in the wake of their parents’ divorce and are working with a private tutor – but stresses they were not, as previously reported, expelled from school. Is Lindsay Lohan going from rehab to ABC’s ”Dancing With the Stars?” Radar Online quotes an anonymous source as saying the show’s producers “have had Lindsay on their wish list of castmates for a long time.” Show reps would not comment on the rumor.
