A source told Us that Mendes, who's already mother to 1-year-old Esmeralda, was spotted hiding her baby bump while posing for a photo shoot in Los Angeles back in February. The Huffington Post has reached out to reps for the couple for confirmation and will update this post accordingly.
Last October, the 42-year-old "Ghost Rider" actress told the "Today" show that her daughter inspired her to take some time away from acting to focus on her family life.
"If I’m even like, ‘Oh, what should I wear? Or, should I do this project? All I have to think about is my daughter and her face, and I know the answer immediately," she said. "She’s my moral compass in a way."
Mendes and Gosling met on the set of their film "The Place Beyond The Pines" in 2011, and welcomed Esmeralda in 2014. The famously private couple have not shared any photos of their daughter.
