Wearing a custom-designed Monique Lhuillier gown, the actress, 35, exchanged vows with CAA agent Toth, 40, in front of 120 family members and friends (including Renee Zellweger, and Alyssa Milano, and Tobey Maguire) in the front courtyard of the Ojai house.
Witherspoon's best friend, Heather Rosenfield, served as matron of honor, and her kids with ex-husband Ryan Phillippe -- daughter Ava, 11, and son Deacon, 7 -- took part in the ceremony. The Oscar winner's young nieces served as flower girls.
The "Tennessee Waltz" was the processional music for Toth and the kids, while Witherspoon walked down the aisle to "Here Comes the Bride." The 20-minute ceremony was officiated by Reverend Jimmy Bartz, founder of Thad's church in Santa Monica, where the couple have been attending weekly Sunday services. The duo exchanged wedding bands designed by jeweler William Goldberg.
Located 90 miles north of Los Angeles, the Ojai ranch -- where the star gardens and keeps horses, donkeys, pigs, goats and chickens -- has been Witherspoon's rural escape for years.
