Reese Witherspoon getting ready for rehearsal

Reese Witherspoon is holding a rehearsal dinner before she gets married on Saturday (26.03.11).

The 34-year-old actress - who is marrying Hollywood agent Jim Toth, who she has dated for just over a year - is reportedly celebrating her impending nuptials early at her Californian home tonight (25.03.11).

She will be joined by her parents John and Betty, her brother John and her two children, Ava, 11, and seven-year-old Deacon, from her first marriage to Ryan Phillippe.

Jim's family, as well as friends of the couple who have flown in for the big day, will also be attending the special dinner before the big day tomorrow.

According to RadarOnline.com, the couple are now fully prepared for the nuptials and white marquees have been erected in the grounds of their remote Libby Ranch home.

Guests will also have the option of pampering themselves beforehand at the nearby Ojai Valley Inn and Spa which costs between $350 and $15,000 a night.

Earlier this month, it was reported that the 'Walk the Line' actress is having a 'Southern Style' wedding with an "intimate" feel to represent her Louisiana upbringing.

A source said: "The Southern theme reflects her roots. Candles and flowers, mostly roses and calla lilies, will be everywhere in white and soft pastels for an intimate feel."
