Barbara Palvin turned 33 on October 8, 2026, celebrating her first birthday since becoming a mother.
The Hungarian model welcomed her daughter, Sylvie, with husband Dylan Sprouse in September.
Birthday tributes on social media offered a glimpse of the couple's new family life.
Palvin shared messages from friends and family on her Instagram Stories, including a video of herself blowing out candles on a cake.
A tribute from Cole Sprouse, Dylan's twin brother, also drew attention.
Cole posted an Instagram Story of Palvin in a park wearing a white sleeveless dress.
The image featured a birthday cake sticker and a stroller, though the baby was not visible.
The subtle stroller hinted at Palvin's new life as a mother without directly showing her daughter.
Cole tagged both Palvin and Dylan in the post.
Palvin and Dylan announced Sylvie's arrival on September 28 through a joint Instagram post.
The family photo showed the couple holding their newborn while watching a Los Angeles Dodgers game, all three in matching team jerseys.
"We took Labor Day literally this year," the couple wrote, suggesting their daughter arrived around the US holiday.
Dylan later revealed on his Wildmen podcast that they had named their daughter Sylvie.
The birth followed the couple's pregnancy announcement at the Cannes Film Festival in May 2026.
Palvin displayed her baby bump on the red carpet, and the couple later revealed they were expecting a girl.
Dylan joked that he was excited to become a "girl dad."
The couple married in Hungary in July 2023 after dating for several years.
Their daughter is their first child together.
A Career Milestone
Palvin's birthday also highlights a modeling career spanning international campaigns and magazine covers.
She first appeared in the SI Swimsuit Issue in 2016, earning Rookie of the Year honors for a shoot in Turks and Caicos with photographer James Macari.
She returned in 2017 for a shoot in Curaçao with photographer Ben Watts, followed by another session in the Bahamas.
Her fourth consecutive annual appearance took place in Costa Rica, photographed by Macari.
During her Bahamas shoot, Palvin described how her relationship with her body and confidence had changed since her first appearance.
"Three years ago when they booked me, I was just really not comfortable in my body and actually, you can see it in the pictures," Palvin said.
"The first one, you see a girl trying to be sexy, a girl trying so hard.
These photos, you see a strong woman who really loves herself and [is] very confident."
SI Swimsuit editor in chief MJ Day also emphasized confidence as an important element of a successful photo shoot.
"Being confident, it's the game-changer," Day said. "It's really the thing that sets a great picture apart from a good picture."
Beyond SI Swimsuit, Palvin is known for her work with Victoria's Secret, where she first walked in a show in 2012 and earned her Angel wings in 2019.
She most recently appeared in the brand's runway show in October 2025, despite previously revealing that she had walked in heels with a broken foot.
Her professional portfolio also includes campaigns for Armani, L'Oréal Paris and Prada, as well as magazine covers for Harper's Bazaar, Elle and Vogue.
Her 33rd birthday comes as she balances her established modeling career with her first year of motherhood.
