VIDEO : Kevin Costner: Stephen Hawking Came Over to Talk About Whitney Houston

Stephen Hawking appears to have a rather strong affinity for Whitney Houston. Kevin Costner appeared as a guest on Tuesday's Jimmy Kimmel Live, where he revealed that the author and physicist stopped by his house unexpectedly in the early 2000s. Costner said that Hawking and an entourage of about 10 people showed up, and it took a while for the Theory of Everything subject to explain the reason for his visit.
