When it came to her engagement last month
, Allison Williams says her fiancé, Ricky Van Veen, totally pulled off the grand move without a hitch.
"I was completely surprised, and the funniest thing about that is that I consider myself someone impossible to surprise and yet I am constantly," the Girls
star, 25, told Late Night
host and good friend Seth Meyers
as she showed off her huge and sparkling engagement ring.
"I'm obsessed with it. I stare at it a lot," a giddy Williams, who has said she dreams of becoming a mom
, shared of the rock. "We're thrilled."
While she offered up no details of how the proposal went down, Williams said the weight of making such a huge life decision definitely is a game-changer.
"It feels a little different, as you know," she told Meyers, who got married
last September. "It just changes the stakes clearly. It's really fun."
It's also changed how Williams, a consummate fan of television's The Bachelor
, watches her fave show.
"Suddenly the show feels real," she said. "I have empathy. I was filled with anxiety for all of the contestants."
's showrunners apparently acknowledged her support: Williams said the show sent her a bouquet of a dozen roses on Valentine's Day with the appropriate message, "Will you accept these roses?"
"And I did," she said. And while she shared in the ladies' journey to find their mate, Williams says she isn't certain whether the show's current star, Juan Pablo Galavis
, is marriage material.
"He is a man that is very complicated. Filled with contradictions. Loves his daughter," Williams offered. "He says 'Look at me' a lot."
