Source: Reese Witherspoon to Wear Monique Lhuillier Wedding Gown.

Reese Witherspoon's wedding to CAA Agent Jim Toth is just around the corner, and friends of the actress are leaking some of the intimate details about her big day.

Earlier this week, it was reported that Reese would wed at her sprawling Ojai estate before the end of the month. Now, yet another detail has emerged: Reese will be wearing a custom gown by Monique Lhuillier, a source claims.

"She's spending most of her time on that dress," the source divulged. If Reese has chosen Lhuillier, she's not the first celeb to do so—Britney Spears, Carrie Underwood and Eva Longoria.

Witherspoon is also reportedly set to cover the May issue of Vogue, which coincidentally hits newsstands right about the time her new romance Water for Elephants will debut in theaters.
