The 42-year-old actress and her boyfriend Ezra Koenig welcomed their baby into the world "months ago", sources told US Weekly magazine.

The couple have yet to confirm the news themselves.

Rashida - who was previously engaged to Mark Ronson and dated John Krasinski, Colin Jost and Jon Favreau - was first romantically linked with the Vampire Weekend singer in 2016 but they have never confirmed their relationship.

The former 'Parks and Recreation' actress previously admitted she wasn't sure she would ever get married.

She said: "Marriage doesn't really buy you anything. I mean, Chris Messina, who is my co-star in ['Monogamy'] is with my very close friend [producer Jennifer Todd].

"They're not married, but they have two kids and they're wildly happy. It doesn't buy you anything. It just buys you a really big s***ty pageant of a wedding to make other people happy.

"Things are changing so much. Especially this country, we have kind of failed with marriage. We're so protective of this really sacred but failed institution. There's got to be a new model. I don't know what it is, but maybe it's like 10 years with a lease to buy or rent to own."

And Rashida - whose father is legendary producer Quincy Jones - admitted it took her a long time not to feel like a "loser" because she wasn't married.

She said: "My life's great! But it's just this weird thing that's been hammered into my head culturally: that's the only way to succeed, that's the only thing that counts for a woman.

"I'm happy, but the fact that I'm not married and don't have kids -- it's taken me a long time to get to a place where I actually am OK with that, where I actually don't feel like I'm some sort of loser."
