The Sister, Sister star, 32, and Housley, 39, tied the knot at an inn and vineyard surrounded by 300 guests. Mowry wore a wedding gown by Carolina Herrera as she exchanged traditional vows with Housley.
"I've always wanted an outdoor wedding with lots of flowers," Mowry tells PEOPLE of the day planned by event planner Mindy Weiss. "I feel so lucky to have this beautiful day marrying my best friend."
Among the bride's eight bridesmaids were maid of honor Andrea Regalado and Mowry's twin sister and matron of honor Tia Mowry.
Housley and his eight groomsmen, including brother and best man Arik, wore tuxedos and Converse sneakers.
"I feel so blessed to be marrying such an amazing man," says Mowry. Adds Housley: "Tamera is beautiful inside out."
Roses for Their ParentsDuring the ceremony, performed by pastor Dudley Rutherford, the couple presented their parents with long stemmed roses.
"We wanted to honor them, because without their love and support we wouldn't be the people we are today," Mowry explains.
For the reception, Mowry changed into a two-piece ensemble by Dolce & Gabbana before joining the guests for a sit-down dinner that includes a four-tiered wedding cake by Sweetie Pies.
For a sophisticated yet rustic wine-country look, event designer Eden Rodriguez decorated wooden farm tables with pale pink and white hydrangeas and roses, olive branches with olives and hundreds of white candles.
For the first dance, the newlyweds danced to Journey's "Faithfully" before surprising their guests with a performance to LL Cool J's "Going Back to Cali."
After a third outfit change by the bride – this time into a dress by Herve Legera, the schedule called for an after – party inside a barrel room with dancing to a DJ from San Francisco's KMEL radio station.
Late night snacks include a taco truck and dessert from Sift cupcakes.
"You can tell they're best friends," says Weiss of the newlyweds. "They have a great mutual respect for one another."
Mowry, who starred with sister Tia on Sister, Sister, next appears on the reality series Tia & Tamera Take 2 this summer on the Style Network.
