Allison Williams is a married woman!

The Girls star tied the knot with her longtime boyfriend, College Humor co-founder Ricky Van Veen, at a picturesque ranch out west this weekend, Us Weekly reports.

Wedding guests included Tom Hanks and Rita Wilson, who plays Williams' mother on the HBO show, as well as Katy Perry, John Mayer, Bruce Springsteen, and Girls creator Lena Dunham.

Williams, 27, and Van Veen, 34, had been dating for three years when they announced their engagement back in February. Judging by a photo Williams posted on Instagram late Saturday, she had the kind of ceremony Marnie would dream of:
