Actor-producer Seth Green, 36, and actress Clare Grant, 30, were married in a private vineyard in Northern California. "We can't believe we found each other," the couple said in a statement. "We've never been happier!"
Grant wore a tiered Oscar de la Renta gown, and Green donned a custom-made suit from Dennis Kim, a source tells PEOPLE. Tarina Tarantino, the designer at whose Sephora launch party the couple were spotted in February, designed the bridal headpiece and the groom's cufflinks. Barry Jay Jewelers designed the bride's wedding and engagement rings.
Adding to the intimacy of the ceremony, Craig Brewer, who cast Grant in the lead of his MTV series $5 Cover, officiated at the wedding.
The nuptials kick off a busy year for the couple. In addition to $5 Cover, Grant also lends her voice to characters in the Adult Swim Emmy-winning animated series Robot Chicken.
Green continues to voice Chris on the animated Fox series Family Guy and next March will be the lead in Disney's feature film Mars Needs Moms. Green will also serve as creative contributor to LucasFilm's upcoming animated Star Wars series – after all, Green is a fan and George Lucas did attend the wedding.
