She's with her! Olivia Wilde revealed that she's expecting a baby girl with fiancé Jason Sudeikis as she tweeted her support for Hillary Clinton on Saturday, September 24.

The House alum announced the news while sharing a new ad from the Democratic presidential candidate that slams Republican rival Donald Trump for his degrading comments about women.

"As someone who is about to have a daughter, this hits me deep in my core. #NeverTrump," the 32-year-old captioned the video.

The video shows girls of all ages looking in the mirror and taking selfies as the former reality TV star can be heard talking about a woman who has a "fat, ugly face" (he was referring to Rosie O'Donnell) and saying that "a person who is flat-chested, it's very hard to be a 10." (His comment was about former Desperate Housewives star Nicollette Sheridan.)

The ad ends with the question, "Is this the president we want for our daughters?"

Wilde announced in April that she was expecting her second child with Sudeikis, sharing a sweet pic on Instagram that showed her and son Otis, 2, patting their protruding bellies.

The couple got engaged in January 2013 after two years of dating and welcomed Otis in April 2014. The Saturday Night Live alum joked earlier this year that they won't walk down the aisle "until weed is legal in every state."

The actress, who lives in NYC with her family, slammed her fellow subway riders on September 14 for not offering her a seat on the train, even though she is obviously heavily pregnant.

"NBD, able-bodied [subway] riders who won't give your seat to a GIANT preggo," she tweeted. "I'll just stand riiiiight next to your head and pray I go into labor."
