Among the guests headed to the Montecito, Calif., nuptials of Kim Kardashian and NBA star Kris Humphries this weekend are Greta Van Susteren and John Coale. The Fox News host and her lawyer husband became pals with the reality star bride when she was their guest at the White House Correspondents’ dinner in 2010.
