Heather Matarazzo planning same-sex wedding

(CBS/AP) NEW YORK - "The Princess Diaries" actress Heather Matarazzo is getting ready for a new role - bride.

The 28-year-old actress, who won an Independent Spirit Award for her work on "Welcome to the Dollhouse," plans to wed longtime girlfriend Caroline Murphy now that New York has legalized same-sex marriage.

"I always wanted a wedding," Murphy says. "Not a trip to City Hall."'

Plans are still in the making, but both seem to favor a bucolic setting in the fall or spring for the ceremony and reception. And with large families on both sides, Murphy expects the wedding list to top 200 guests.

For the ceremony, Matarazzo envisions wearing a simple, off-white dress, but has yet to find the right one. "When I see it I will just know," she told the Associated Press.

Murphy, a recording artist currently working on her first album, says she'll likely wear a white pants suit, "but a sexy one."

Engaged for three years, the couple originally planned to marry in California two years ago. But voters eliminated same-sex marriages before they could plan the ceremony. Now, they are hoping impending court challenges don't achieve the same result here before they say, "I do."

Time is important because they're both eager to start a family. "We've always talked that Caroline would have a child first, and then I will go," Matarazzo says. After that, they plan to adopt.
