There's now double the love in the Olivia Wilde and Jason Sudeikis household. They've welcomed their second child.

Olivia took to Instagram on Oct. 15 to announce the arrival of her adorable baby girl, Daisy Josephine Sudeikis.

The actress posted the sweet photo on social media a few days after their bundle of joy arrived, noting that Daisy was born on International Day of the Girl on Oct. 11, 2016.

There goes the neighborhood. Daisy Josephine Sudeikis. Born, like a boss, on #internationaldayofthegirl. ❤️

Daisy joins 2-year-old big brother Otis, who just happens to be insanely adorable.

Olivia revealed the gender of their newest bundle of joy in late September while vocally supporting presidential candidate Hillary Clinton.

"As someone who is about to have a daughter, this hits me deep in my core," she tweeted on Sept. 24 while retweeting one of the democratic nominee's campaign videos.

Both Olivia and Jason have been vocal about their desire to add to her brood.

In April, she told People, "I'm desperate for more [kids]. I love my siblings so much and Jason has incredible siblings too. The more the merrier."

In a recent interview with Entertainment Tonight the actor was asked how many children he and his lady love want. "I'll say two until three becomes the number," he said, "and then four and then etcetera, etcetera."

In late February Olivia gushed about motherhood, saying that she's a better person because of Otis, who she used to announce her second pregnancy in April.

"It's made me a better human being, it's made me a better artist, it's made me a more grateful person, a more tired person. Everything it does to every single mother, that's the most amazing thing about it."

She continued, "You become a mother and you go through kind of the same experience. I kept thinking about that during child birth and I think about it every day since."

"It's just something that unites us and that's a really, wonderful, powerful thing so I want to channel that into a role that would be help me be really helpful in some way."
