Sarah Silverman and Jimmy Kimmel are getting back together — on TV anyway. Silverman will appear as a guest on Kimmel’s late-night show Thursday. The couple split in July after five years of dating, but there have been sightings of them on the town recently. Rapprochement? … In another setback on her Rock Witchu Tour, Janet Jackson has lost her opening act: LL Cool J. The rapper’s publicity firm announced Monday that he has dropped out as the opener for Jackson because of unnamed scheduling conflicts. … On Friday, Fall Out Boy will make another attempt to enter the Guinness Book of Records when it takes aim at the mark for most radio interviews by a pair within 24 hours.

FOB’s Pete Wentz and Patrick Stump will make the effort, MTV.com reports.
