They've got a bun in the oven!

Eva Mendes is pregnant with her second child with her longtime boyfriend, Ryan Gosling, Us Weekly reports. The 41-year-old actress and Gosling already shared 17-month-old daughter, Esmeralda. Sources say Mendes has been working on hiding her baby bump, but it was visible during a recent photo shoot in Los Angeles.

Whether or not the duo are expanding their brood, they likely won't comment on the news anytime soon. The parents have famously kept their daughter, whom they welcomed on September 12, 2014, out of the spotlight and have never shared a photo of her. However they did share how their daughter got her super cute moniker.

"We love The Hunchback of Notre Dame, we loved the name, the cartoon and the novel... it just kind of kept coming back to us," Mendes shared. "It's actually a very popular Latin name, so it's easy for my father and certain family members that still don't speak English to pronounce. That was a good selling point."

Gosling and Mendes met on the set of "The Place Beyond the Pines" in 2011 and have been dating ever since.
