"American Wedding" star Alyson Hannigan has held an American wedding of her own: She's married her former "Buffy the Vampire Slayer" costar Alexis Denisof, according to published reports.

The pair tied the knot Saturday at the Two Bunch Palms resort near Palm Springs, Calif. It's the first marriage for both.

While few other details were released, Hannigan, 29, did speak at length about Denisof, 37, to PEOPLE last August, at the time "Wedding" was released.

The two met on the "Buffy" set during the 1999-2000 season, though he didn't get around to popping the question until last January -- at a moment when she had food in her teeth.

As she recalled, "We were driving up to his mom's house for Christmas. It was this wonderful road trip and we were up in Sonoma and Napa (Calif.). We bought all these beautiful foods and Alexis found this lake pretty close by, so we went to the lake. I'm swallowing the food, and then he just started saying these beautiful, wonderful things.

"The whole time I am getting kind of frustrated, like, 'Why does he always do this? He says the most romantic things and it would be the perfect way to propose and then he doesn't propose.'"

And then, suddenly, he did. "I was like, 'Huh?'" she said. "Everything in my brain just screeched to a halt. I wish I had TiVo, so I could rewind the whole thing. ... It was a complete surprise. But I knew he meant it because he had a ring."

Next up for the couple, professionally at least: Hannigan will pop into FOX's "That 70's Show" for a stint beside Ashton Kutcher as both their characters enroll in a police academy. She's also signed a deal with NBC to star in her own sitcom, aimed for fall 2004, says the Hollywood Reporter.

Denisof, meanwhile, continues his role as Wesley Wyndham-Pryce on "Angel."
