She won't be walking down the aisle until Saturday, but Reese Witherspoon won't have to wait to start the celebrations, as Breaking Celebrity News is  exclusively reporting she will be kicking off the festivities with a rehearsal dinner Friday night.

The bride-to-be and her future husband, Jim Toth, will be joined by her parents, John and Betty, her brother, John and her children, Ava and Deacon for a pre-wedding celebration at the Ojai, California home where she is set to say "I Do."

The happy couple has also invited a few close relatives from Toth's family as well as friends who have flown in for the big event.

The group will be catered for at the luxury Libby Ranch home which is currently being transformed into a wedding wonderland with white marquees erected on the lush, green grounds.

As Breaking Celebrity News first reported, the wedding will take place this Saturday at the retreat in the remote town, 90-minutes north of Los Angeles.
