Jim Toth and 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.
Tucked away between rolling hills, the Ojai Valley property offers Witherspoon and her kids plenty of privacy.
Sources have told PEOPLE that the kids bonded easily with Toth early on in his relationship with their mom.
"He's a grownup who's really ready to take the next step," a source told PEOPLE
about Toth around the time of the pair's engagement. "He's a family-oriented guy, and that's all she ever really wanted."
And in the run-up to the nuptials, Witherspoon was "very giddy," added the insider, and "excited to see what the future holds."
