Kim Kardashian is back in Los Angeles after a two-day trip to Paris, France, where she reportedly shopped for wedding essentials at Balmain, Lanvin and Azzedine Alaïa, with a little help from star tennis player Serena Williams. The 33-year-old media personality recently wore a Lanvin wedding gown on the cover of Vogue, prompting speculation that she'll choose the French designer for her actual dress. "She's picked out her dress, and she beyond loves it," a source told E! News on Wednesday. Kardashian reportedly plans to marry fiance Kanye West in a "confidential" civil ceremony sometime this week, before they throw a huge party in Paris next month.
