Carey Mulligan's family is outnumbered by girls!

On Thursday, the Maestro actress, 38, attended the 2023 Variety Power of Women Los Angeles gala, confirming to Entertainment Tonight that she had recently welcomed a baby girl into her family.

"Oh, she's great. Great. Good baby, 10 out of 10 so far," Mulligan told the outlet, adding a thumbs up. "We'll see how long that lasts."

While recently speaking with Vogue for their November cover story, the She Said actress confirmed that she had welcomed another baby with her musician husband, Marcus Mumford, 36.

In the article, the interviewer noted that Mulligan was six weeks postpartum at the time of their meeting, sharing that the actress entered "a London coffee shop with a bemused gesture at the yellow diaper-leak stain streaked across her blouse."

Carrying the infant, Mulligan then said to her baby, "I'm going to change you, and then we're going to find Mum another shirt."

There was no further mention of the baby, whose name is still unknown.

The couple shares daughter Evelyn Grace, 7, and son Wilfred, 5.

Last year, Mulligan chatted with PEOPLE about her role in the film She Said and opened up about her experience coping with postpartum depression after the birth of her first child.

In the film, Mulligan plays New York Times investigative reporter Meghan Twohey, who, with journalist Jodi Kantor (played by Zoe Kazan), published a bombshell Harvey Weinstein investigation in 2017 that would go on to spur a worldwide #MeToo reckoning.

When Twohey took up the towering investigation with Kantor, she was on maternity leave coping with postpartum depression, and Mulligan told PEOPLE: "One of the parts of the script that hit me initially the most was Megan's experience with postnatal depression. I had a very similar experience with my first child seven years ago, and felt very alone, and very scared, and also very confused by the whole experience."

For Mulligan, "it was really going back to work in some form," shooting the 2015 film Suffragette, "that was the thing that got me on the road to finding myself again with incredible support around me."
