With nature and family as themes, actress Alyssa Milano wed Hollywood agent David Bugliari at his family’s estate in New Jersey on Saturday, her rep confirms exclusively to PEOPLE. Milano, wearing a custom gown by Vera Wang and holding a bouquet of lily of the valley flowers, walked down an aisle strewn with cream-colored rose petals and natural grass to the tune of John Lennon’s “Imagine.”

The couple exchanged traditional vows under a wrought-iron gazebo decorated with willow, calla lilies and roses. Among the guests was actor Bradley Cooper, a friend of the groom.

“We wanted a wedding that was reflective of who we are as a couple” says Milano, who calls meeting her husband in 2006 “a lovely gift.”

Following the ceremony, wooden signs directed guests to the cocktail area, decorated with rattan furniture and hay bales serving as cocktail tables. Dinner was served family style on rustic farmhouse tables in a tent with wood flooring and wrought iron chandeliers. Event planner Colin Cowie created just the right atmosphere for the family-oriented couple.

“My Italian family still eats Sunday dinner together every week,” says Milano. “We wanted to capture the same feeling with people passing around beautiful bowls of food and talking and laughing.”

Bugliari, an agent at the Creative Artists Agency, “proposed to Milano, 36, last December with a ring he designed and made by Jim Lavi at Daniel Jewelry in La Jolla, Calif.
