Olivia Wilde has taken to Twitter to take to task New York City subway riders who would not offer the heavily pregnant actress a seat.

Using internet slang for “no big deal,” the “House” and “Vinyl” star tweeted Wednesday to her 1.75 million followers, “NBD, able-bodied riders who won’t give your seat to a GIANT preggo. I’ll just stand riiiiight next to your head and pray I go into labor.”

Most people responding to the tweet expressed support for any pregnant woman in such a circumstance, with many commenting on riders’ lack of chivalry. Some questioned politely why film and TV star Wilde, 32 — the daughter of lauded journalists and authors Leslie and Andrew Cockburn and the fiancee of fellow star Jason Sudeikis — was taking a subway rather than more upscale transportation. However, one Twitter commenter, Kyle (@kps427), a self-described “small business owner, NY Giants & Red Sox fan, and proud Episcopalian” who has since made his account private, tweeted, “1. I didn’t tell u to get pregnant 2. Get an Uber (you can afford it) 3. I paid the same amt as you for the subway ride,” according to E! News.

“1. Eat a bag of [expletive],” Wilde responded. “2. That is all.” Shortly afterward, singer John Legend tweeted supportively, “@kps427 @oliviawilde deplorable.”

Wilde announced on April 18 that she and former “Saturday Night Live” star Sudeikis, who turns 41 on Sunday, were expecting their second child. They have a son, Otis, 2. The couple, who reportedly have dated since November 2011, confirmed in January 2013 that they had become engaged.
