Wilde, 32, and the Saturday Night Live alum, 41, announced in April that their son, 2-year-old Otis, was going to be a big brother.

The couple — who got engaged in January 2013kept mum about the baby's gender. That is, until Wilde slammed Republican presidential nominee Donald Trump in a tweet in September. "As someone who is about to have a daughter, this hits me deep in my core. #NeverTrump," she captioned a video, which featured clips of the business mogul, 70, bashing women's looks.

The Vinyl star continued to hit the red carpet up until her due date. She attended an NYC event that honored Martin Scorsese on September 21 and presented at the Global Citizen Festival in Central Park two days later.

Last year, Wilde opened up about motherhood and Otis' hobbies. "He’s so smart and just plays his piano all day long," she told Us Weekly exclusively. "He’s really musical, so we’re trying to encourage that."

Wilde and Sudeikis began dating in 2011. In April, the Horrible Bosses actor joked about why they haven't tied the knot just yet. "I feel like we are [good] in many, many ways," he said during an appearance on Watch What Happens Live. "I mean, I believe we won't get married until weed is legal in every state, gosh darn it!"
