E! Celebrates 20 Years of Entertainment

Last night in Los Angeles, an eclectic mix of personalities strutted down the red carpet to celebrate two decades of pop culture at the E! 20th anniversary party held at West Hollywood's London Hotel. Spotted were LA nightlife regulars, including all the Kardashian ladies, Mr. E! himself Ryan Seacrest, and some surprise appearances like rapper Master P and rocker Richie Sambora. Funny girl Chelsea Handler was noticeably absent. See who wore what to honor our go-to channel for all things entertainment.
