REESE WITHERSPOON got married at her estate in Ojai, California on Saturday night.  Her new husband is showbiz agent Jim Toth.  He's 40 . . . Reese is 35.  Reese and Jim started dating in January of 2010.  They got engaged in December. This was probably one of the most star-studded weddings in quite some time.  Guests included Renee Zellweger, Tobey Maguire, Robert Downey Jr., Alyssa Milano, plus Sean Penn and Scarlett Johansson. Part of Reese's pre-wedding prep included apologizing in advance to her neighbors for the chaos that was about to ensue. A source says, quote, "Reese sent nice personalized letters to all the neighbors last week.  "She informed us that she and Jim were having their wedding at her home and apologized ahead of time for all the construction and all the cargo trucks that would be coming in and out of the community."

 Here's some pics from some helicopter flying over the event.
