Reese Witherspoon: Monique Lhuillier lined up to design Reese Witherspoon’s wedding gown!

Reese Witherspoon is making plans for her wedding day! Us Weekly magazine reports that the actress — who’s engaged to Hollywood agent Jim Toth — has chosen her wedding gown!

Reese will reportedly rock a Monique Lhuillier design when she walks down the aisle.

“She’s spending most of her time on that dress,” a source said.

Reese’s nuptials will take place at the star’s Ojai, Calif. ranch. “The wedding will be in the early evening in one of the fields behind the house,” reveals a pal.

Recent reports claimed Witherspoon is planning an “intimate” wedding to Toth on March 26.

The blonde beauty is said to have been working with celebrity event maestro Yifat Oren to plan a small “Southern-themed” ceremony with around 100 guests at her sprawling estate in Ojai Valley, California.

“The Southern theme reflects her roots. Candles and flowers, mostly roses and calla lilies, will be everywhere in white and soft pastels for an intimate feel,” a source said.

“Reese knows exactly how she wants the wedding to be. Comfortable, but very classy and incredibly romantic.”

The 34-year-old star — who has two children, Ava, 11, and Deacon, seven, from her seven-year marriage to actor Ryan Phillippe — is determined to get her special day right, after concluding she didn’t know what she wanted from her first nuptials.

“Reese feels that when she planned her wedding to Ryan, she was too young and didn’t really know what she wanted,” the source added.

“This time, she’s certainly getting it all right.”

However, Reese is finding it difficult to find the perfect dress for the occasion.

“She had a hard time choosing because she wants refined glamor but also wants to show off her great figure,” said the pal.
