Olivia Wilde is expecting a baby girl.

The 32-year-old actress who is heavily pregnant with her fiance Jason Sudeikis' second child - a sibling for their two-year-old son Otis - has revealed while supporting presidential hopeful Hillary Clinton that she will be welcoming a daughter into the world in the coming months.

She retweeted a video posted by the Democratic candidate and wrote: "As someone who is about to have a daughter, this hits me deep in my core. #NeverTrump (sic)"

The video shows footage of young girls along with sound bites from Republican candidate Donald Trump's interviews, and ends with the question: "Is this the president we want for our daughters?"

The Vinyl actress recently revealed she is raising Otis to be a feminist.

She said: "I like to think he's already a little feminist. And he is. I want to promote the idea that the definition of feminism is equality and it's something that's not difficult to teach children because they are born with that sensibility.

"They are only taught to separate people and value them differently once they get older."

And Olivia also opened up about her controversial 2014 shoot, where she decided to breastfeed her son for the magazine's photos.

She added: "I've learned a lot about that debate since that photo shoot and certainly since becoming a mother. One thing that is very clear to me is that it should be every individual woman's choice what she wants to do. But once she makes that choice, she should be publicly permitted to do that in whatever way she needs to. Certainly there should be no pressure on women to breastfeed, or they are made to seem like they are terrible mothers. I think that's really unfair.

"It was an interesting experience because that photo shoot came out of a very organic moment of having to feed my son because it was just my choice to breastfeed. But I did not in any way intend to shame women who had chosen not to breastfeed for whatever reason. It's a complex issue, but the one thing that's not complex is that people should be allowed to breastfeed wherever they want, whenever they want."
