Allison Williams Just Got Married! See The Stunning Pic

That dress, you guys.

When you're a celeb in the public eye, it's tough to plan a wedding on the hush-hush – but not impossible (just ask Jennifer Aniston!) So we're sending equal amounts of props and congratulations to Allison Williams and Ricky Van Veen, who got married on Saturday in Wyoming.

The "Girls" star announced the nuptials to the College Humor co-founder via her Instagram account. And she is wearing that couture Oscar de la Renta gown.

The celebration took place at Brush Creek Ranch in Saratoga, Wyoming, and – according to People – the guest list included Williams' "Girls" co-stars Lena Dunham, Jemima Kirke and Zosia Mamet, along with Katy Perry, John Mayer and Seth Meyers. More pics, please!
