Allison Williams married Ricky Van Veen on a Wyoming ranch wedding on Saturday in front of family and many celebrity friends.
The "Girls" star, 27, wore a white gown by Oscar de la Renta as her father Brian Williams walked her down the aisle, according to People. Oscar-winner Tom Hanks officiated the ceremony held at Brush Creek Ranch in Saratoga, Wyo.
"The magical setting featured a small creek and spectacular views," a source told People. "It was a stunning ceremony."
The star-studded guest list included Williams' co-stars Lena Dunham, Zosia Mamet and Jemima Kirke as well as her TV mom Rita Wilson (Hanks' wife). Katy Perry, John Mayer, Barry Diller, Diane Von Furstenberg, Bruce Springsteen, Seth Meyers and another 150-200 guests were in attendance.
The festivities began on Thursday when guests arrived and then celebrated the couple's rehearsal dinner on Friday, according to Us Weekly. Williams and Ween also set up a host of activities for their guests to enjoy the day before the wedding.
"Guests arrived to gorgeous weather," the source told People. "On Friday, everyone enjoyed the ranch life and did a variety of activities organized by the couple."
College Humor co-founder Veen proposed to Williams in February. They kept their wedding plans quiet during the controversy surrounding her father when NBC News suspended him for lying on the air.
