"Stephen Moyer and Anna Paquin were married on Saturday evening in Malibu surrounded by their family and friends," the couple's reps tell PEOPLE.
Paquin – wearing a white halterneck gown and Neil Lane jewelry with her hair in an updo – and Moyer, clad in a dark suit, exchanged vows at sunset under a white tent at a beachside villa.
"It was a beautiful evening to get married and the sunset was gorgeous. Anna and Stephen seemed very excited to celebrate their wedding day," a source tells PEOPLE.
Celebrity guests included True Blood creator Alan Ball, costars Ryan Kwanten, Sam Trammell, Rutina Wesley and Carrie Preston as well as actor Elijah Wood.
The good news comes after a year-long engagement for the stars of the hit HBO series. Moyer, 40, proposed with a vintage-style ring on the beach last August.
"It’s great to have the freedom to enjoy your work and not feel like you're leaving your other life behind," Paquin, 28, says of the couple's relationship. "It’s a pretty sweet setup."
