Grace Gummer and Mark Ronson are expecting their second child together.
The 38-year-old actress - who is the daughter of Hollywood star Meryl Streep - recently debuted her growing baby bump at Justin Theroux's annual holiday party at Pebble Bar in New York City.
The loved-up couple - who tied the knot in 2021 - haven't actually made any public comment about their pregnancy, and have always made a concerted effort to keep their romance out of the spotlight.
Grace actually announced her first pregnancy in similar fashion back in October 2022, when she wore a form-fitting red dress to W Magazine's 50th-anniversary party.
But at the time, the celebrity couple - who welcomed a baby girl in 2022 - chose to remain tight-lipped about the pregnancy, and have since kept their family life very low-key.
By contrast, Mark announced news of their marriage via a social media post in 2021, when he shared a sweet tribute to the actress on Instagram.
Mark, 49 - who was married to actress Josephine de La Baume between 2011 and 2018 - took to the photo-sharing platform to pay a glowing tribute to his wife.
Alongside a romantic portrait from their wedding day, Mark wrote on Instagram in September 2021: "To my truest love...out of nowhere, you made 45 hands down the greatest year of my life. And i'm sure it took me 45 years to become the man worthy of your love. I hope I spend every one of these birthdays by your side til my last day. And beyond. (sic)"
Mark subsequently added: "Forever and ever yours [heart emojis] (and yes, we got married) (sic)"
