Reese Witherspoon is legally married.
The Oscar-winning Legally Blonde actress, 35, tied the knot with her very own leading man, entertainment agent Jim Toth, 40, on Saturday evening, her rep confirms exclusively to PEOPLE.
The couple, who became engaged in December, tied the knot in a private ceremony at Witherspoon’s ranch estate in Ojai, Calif.
A pre-wedding cocktail hour took place before the 20-minute ceremony, which started a bit late. Witherspoon walked down the aisle to “Here Comes the Bride.” Monique Lhuillier designed the wedding dress.
Those in attendance included Witherspoon’s children (with her first husband Ryan Phillippe), Ava, 11 and Deacon, 7, as well as Renée Zellweger, Sean Penn with Scarlett Johansson, Tobey Maguire, Robert Downey Jr. and his wife, Susan, and Alyssa Milano and her CAA agent husband, David Bugliari.
