Julia Roberts
With Sly Stallone crushing Julia Roberts in this weekend's box office, Hollywood is asking what the heck happened to America's favorite pretty woman? Experts tell me that surprisingly (okay, more like shockingly), omnipresent and self-promoting stars like Kim Kardashian are to blame.

"Julia has only headlined two films in almost 10 years -- discounting cameos and ensembles -- and so, like any paramour who plays hard to get, I think she lost her luster with audiences." Joe Neumaier, film critic for the New York Daily News, tells me. "The women who came of age with her since 'Pretty Woman' may associate with what her character goes through in 'Eat Pray Love,' but they may have gotten used to Julia in small doses."
