Allison Williams got married in a ceremony officiated by Tom Hanks on 19 September.
The 'Girls' star wed her beau, CollegeHumor co-founder Ricky Van Even, at the exclusive Brush Creek Ranch in Saratoga, Wyoming, with guests including her co-star Lena Dunham, John Mayer and Katy Perry.
According to the New York Post newspaper, Oscar winner Tom oversaw proceedings at the sweet ceremony, while crooner John serenaded the couple.
The 27-year-old beauty was walked down the aisle by her father, NBC news presenter Brian Williams, and wore a stunning Oscar de la Renta gown.
Other guests include Allison and Lena's fellow 'Girls' stars Zosia Mamet and Jemima Kirke, as well as Tom's wife Rita Wilson, who plays the brunette actress' mother on the HBO comedy.
Allison and Ricky, 34, kept their wedding top secret and even asked guests to fly into a different city, where they were picked up and taken to the luxury ranch location.
A source said: “The wedding is being kept so secret that guests are being asked to fly to Denver, where they will be picked up and taken to the location, which is thought to be somewhere in Wyoming.
“The accommodations for all guests are being paid for and then many of the guests are flying to LA together for Sunday's Emmys.”
Allison previously admitted she had delayed her wedding to Ricky - to whom she has been engaged since February 2014 - due to the controversy surrounding her father Brian. The NBC news presenter was suspended earlier this year for embellishing details of his experiences while reporting on the front lines of the Iraq War and Hurricane Katrina.
In February, Allison, 27, said: “This has been a really hard time. Obviously [it's] toughest on my dad, who is sort of bearing the full burden of the responsibility for it ... Current events started happening so that derailed [wedding plans] a little bit.”
However, despite all the drama leading up to it, Williams' wedding was “stunning”, with one guest saying the serene wedding was beautiful.
A source told PEOPLE.com: “The magical setting featured a small creek and spectacular views. It was a stunning ceremony.
“Guests arrived to gorgeous weather. On Friday, everyone enjoyed the ranch life and did a variety of activities organised by the couple. They had a rehearsal dinner Friday night at the ranch.”
Guests at the wedding included Allison's father Brian Williams, who gave her away, her 'Girls' co-stars Lena Dunham, Jemima Kirke and Zosia Mamet, Katy Perry, John Mayer, Seth Meyers and Bruce Springsteen.
Allison, 27, and Ricky, 34, got engaged in February 2014 and the actress admitted at the time the proposal was a “total surprise”.
She said: “I was completely surprised. A total surprise, the best kind of surprise.”
