SOLVANG, Calif. – Now she’s Mrs. Congeniality.

Actress Sandra Bullock wed her bad-boy boyfriend, tattooed reality TV star Jesse James, at a horse ranch Saturday in California wine country.

More than 300 friends and family attended the sunset wedding, including Metallica frontman James Hetfield, actors Jamie Lee Curtis, William Shatner and Regina King and “George Lopez” star Constance Marie, “Entertainment Tonight” reported.

Bullock, who turns 41 later this month, wore a white lace dress designed by Angel Sanchez.

She walked down the aisle to a tape of her late mother, opera singer Helga Bullock, performing Bellini’s “Casta Diva,” according to “ET.”

“She looked beautiful,” one guest told People magazine. “She was incredibly happy.”

James, 35, who stars on the Discovery Channel’s “Monster Garage,” drove to the ranch Saturday behind the wheel of one of his red monster pickup trucks.

Guests, who assembled under white circus tents, weren’t told they were attending a wedding until they arrived.

Shuttle buses took the guests to the Folding Hills Ranch in Solvang, Calif., from hotels in nearby Santa Barbara.

At the ranch, they danced to the bluegrass music of Cousin Lovers and ate wedding cake baked by Bullock’s sister, Gesine Prado.

This is the first walk down the aisle for the star of “Speed” and two “Miss Congeniality” flicks, though she was once engaged to actor Tate Donovan and romantically linked to Matthew McConaughey.

The groom has been to the altar twice before, with Karla James and porn star Janine Lindemulder. He has a son and two daughters from those marriages.

From a Janine biog on the ‘Net: She [Janine] retired again in September of 2002, due to her upcoming marriage with Jesse James (of West Coast Choppers and Monster Garage). Jesse documented their courtship and marriage – and rocky divorce a year later – in his documentary Motorcycle Mania 3. Jesse dumped her, seven months pregnant, for actress Sandra Bullock. Jesse is also demanding a DNA test to prove the child is his, and has filed a restraining order against Janine due to her physical abuse of him.
