Jessica Biel is totally a Valli girl!

As previously reported, the 30-year-old Total Recall star donned custom Giambattista Valli -- a pink and white creation -- to wed Justin Timberlake in southern Italy Oct. 19.

On Wednesday, the famed designer's rep confirmed in a statement that Biel did indeed wear a custom haute couture gown on her very special day.

"The strapless gown of silk mousseline and silk organza consisted of a light pink floral motif and ruffles. The veil, which consists of Biel’s' heirloom pearls, was also created for her by Giambattista Valli," the statement reads.

What's more, Biel's bridal party -- including the mother of the bride (Kimberly Biel) and mother of the groom (Lynn Harless) -- wore Giambattista Valli Haute Couture gowns to the ceremony. Adds the rep: "jessica wore four looks with shoes and clutches from the Giambattista Valli S/S 2013 collection to events leading up to the ceremony."

Biel and Timberlake, 31, hosted 150 guests for a week-long celebration at the Borgo Egnazia resort -- and were showered with flower-shaped petals after exchanging their vows at the hotel's chapel. (Two folks not invited to the bash? Timberlake's former *NSYNC bandmates Joey Fatone and Lance Bass.)
