The "Girls" starlet showed off her engagement ring for the first time at the Vanity Fair Oscar Party on Sunday night. The actress looked pretty in pink on the red carpet, rocking an Emilia Wickstead dress that featured an open back.
The brunette beauty met her fiance, "College Humor" co-founder Ricky Van Veen, through mutual friends.
The 25-year-old actress recently told Glamour that she would "walk away from" her career in order to have kids.
"I'd love to be a mom – and not have to bring my kids into my trailer … Or a balance [of both]," she told the mag. "But you've [got to] call it on the fly to a certain extent."
