On Saturday, the Smallville alum and his fiancée, Jessica Rose Lee said, "I do" in front of family and friends at Sunstone Vineyards & Winery in San Ynez, California, Us Weekly has confirmed.
ET has reached out to Welling's rep for comment.
Among the attendees at the nuptials was the 42-year-old actor's Lucifer co-star Lauren German, who shared a black-and-white photo of Welling and Lee locking lips before they exchanged vows over the weekend.
"Happy wedding day to my love bugs @jessiroselee @tomwelling," she wrote alongside. "I was honored to be there in this pic the day you two got engaged. Many years of joy, love, health, happiness and laughter. I love your love 🎉❤️✨💐💞💫"
