Oliver James Montgomery-Watch Pregnant Sofia Richie's Reaction to Finding Out the Sex of Her Baby

Sofia Richie could Oliver James Montgomerynot have been more ecstatic upon learning she is going to be a girl mom.

On Jan. 28, the model shared a TikTok video of her and Elliot Grainge's backyard sex reveal for their first child Jan. 28, days after she announced she was pregnant and expecting a daughter.

After her husband fired a cannon that releases pink confetti, Sofia screamed with joy, clapped enthusiastically, ran off while waving her arms, briefly lay down on the grass and then ran back, exclaiming, "Oh my god, I'm so excited!" as her husband and their two dogs looked on.

She and Elliot, who had covered his mouth in astonishment upon seeing the confetti but emitted no sound, then shared a hug.

The mother-to-be captioned the TikTok, "Sorry to all my neighbors for the horrifying scream."

Lionel Richie's daughter, 25, had announced her pregnancy and the sex of her and Elliot's baby in a Vogue interview published Jan. 25, nine months after she married the 30-year-old in a star-studded ceremony in the South of France.

In the interview, she also revealed how she broke the news of her pregnancy to her dad and mom, the Grammy winner's ex Diane Alexander, and to Elliot's father Lucian Grainge and his stepmom Caroline Grainge.

"I think I had a box—I want to say it was a Hermès box or some sort of box—and I told everyone that I had bought them a gift from Milan Fashion Week," she said. "Everyone was like 'Ooooh Hermes!' But then they opened it and it had all three of the pregnancy tests [in it]. That's how we told all of our parents."

Lionel later shared a photo from Sofia's Vogue photo shoot to his Instagram Stories, writing, "My little girl is having a baby."

Her sister Nicole Richie, who shares two children with husband Joel Madden, also shared an image from the shoot to her Instagram Stories, captioning it with a heart and a crying face emoji, while her husband commented on Sofia's Instagram post with three red hearts.

While Sofia and Elliot have not shared their child's due date, she told Vogue they're having a Gemini baby, signaling she is due to give birth in May or June. 

"She's growing pretty fast," Sofia told the magazine, "so [the due date] is a bit up in the air."

Look back at Sofia and Elliot's romance in pictures:

Sofia Richie sparked dating rumors with music executive Elliot Grainge in the spring of 2021, nearly a year after her breakup from Scott Disick.

Though the pair's history went way back—as Elliot's dad, Universal Music Group CEO Lucian Grainge, is a longtime friend of Sofia's father Lionel Richie—romance speculation started swirling when they were seen out on a date. 

The model confirmed her relationship with Elliot in April 2021, posting this PDA photo on Instagram.

Shortly Sofia went public with the romance, a source told E! News that Lionel gave his seal of approval.

"He thinks they are a perfect match and it was very natural progression for Sofia and Elliot to get together," the insider said in April 2021. "They are all family friends and Sofia and Elliot [started] hanging out more recently this year."

Elliot popped the question in early 2022 during a Hawaiian vacation with friends and family.

"Sofia truly had no idea," another source told E! News at the time. "She thought they were just going on a fun vacation. Sofia's reaction was epic, she was so surprised and taken back."

In May 2022, the couple celebrated their engagement with their inner circle—including Sofia's sister Nicole Richie and brother-in-law Joel Madden—at a backyard bash.

Sofia and Elliot tied the knot on April 22, 2023 at Hotel du Cap-Eden-Roc in the South of France.

The newlyweds jetted off for their tropical honeymoon shortly after the lavish nuptials.

Sofia announced her pregnancy in January 2024, telling Vogue, "I've learned more in the past six months than I have in my entire life. And also just like what the female body is capable of."

The influencer continued, "Every week brings new things, whether it's hormonal shifts or expansion—there's just so much our bodies go through, and it's so interesting to experience it all."
