*Barely a week after her engagement, Tamera Mowry is already dishing about her scheduled May 2011 wedding, which is currently in the planning mode.

“I’m so excited,” she tells E! News of her engagement to Adam Housley, a Fox News correspondent. “It is going to be a big wedding, probably 400 people with seven bridesmaids and groomsmen.”

Twin sister Tia Mowry is her maid of honor, her brother Taj is a groomsman, the dress is by Vera Wang and the wedding location has already been secured.

“Adam’s family owns a winery in Napa, Calif., but the wedding will take place at a nearby estate,” the former star of “Sister, Sister” says. “We want this wedding to respect us. I was courted in Napa and fell in love with the city. Wine has become a big part of our life together.”

Housley adds, “Our families get along great and her brother is one of my closest friends. We’re very excited. Tamera is my best friend and I love her.”
