Grace Gummer is pregnant, expecting second child with Mark Ronson

Grace Gummer and Mark Ronson are going to be parents of two!

The couple revealed at the music producer’s annual holiday party Thursday night that they are expecting their second child.

The actress, 38, showed up to the festive fête in a fitted red T-shirt dress, debuting her baby bump.

The pair was all smiles as they posed for photos and took to the dance floor alongside some of the star-studded guest list, which included Chris Rock, Don Lemon, Dianna Agron and Aziz Ansari, to name a few.

Ronson, who wore a blue pinstriped button-down shirt and an arm sling, hosted the event alongside pal Justin Theroux.

The party took place at celeb-loved Pebble Bar in New York City and featured a performance by Ghostface Killah.

While Gummer’s famous parents, Meryl Streep and Don Gummer, were not there to celebrate, her sister Louisa Jacobson and sisters-in-law Samantha Ronson and Annabelle Dexter-Jones were notably in the crowd.

The pair’s reps did not immediately respond to Page Six’s request for comment.

The “Mr. Robot” star began dating the Grammy winner, 49, in 2020, and he popped the question just one year later.

The pair said “I do” in August 2021. Although they were originally planning a large celebration, they whittled it down to an intimate family affair due to the COVID-19 pandemic.

The “Homesman” actress revealed her first pregnancy at W magazine’s 50th anniversary party in October 2022. She debuted her baby bump in a ribbed red dress, reminiscent of the one worn Thursday.

One of the hitmaker’s sisters confirmed five months later that the couple had welcomed their first child, a daughter named Ruthie.

“[Grace] just had the baby. She’s two and a half months now,” Dexter-Jones told People at the time. “She’s stunning.”

Around the same time, Page Six obtained pictures of the new parents out on a morning stroll with the little one.

Prior to their relationship, Mark was married to French actress Joséphine de La Baume from 2011 to 2018. Grace, for her part, was married to musician Tay Strathairn for less than two months before ending things in 2019.
