The actress is set to marry Hollywood agent Jim Toth within the next couple of weeks, and according to a source, Lhuillier is 'spending most of her time on that dress'.
According to Us magazine, the 34-year-old has been preparing for her big day with 75-minute hot vinyasa yoga classes and body scrubs and facials from Ona Spa.
And she has also decided to hold the ceremony at her ranch in Ojai, California. 'The wedding will be in the early evening in one of the fields behind the house,' an insider said.
