They haven't introduced their daughter to the world yet, but at least two other people have gotten to meet Ryan Gosling and Eva Mendes' daughter, Esmeralda!

Eva Mendes Suffering From Depression?

According to The Daily Mail, the couple were recently invited over for lunch with Brad Pitt, 51, and Angelina Jolie, 39, at the superstar couple's sprawling Los Feliz mansion, as the two actors try to get to know each other better ahead of shooting their film The Big Short.

"Brad and Ryan have become really close buddies," a source said. "And Eva has been a huge fan of Angelina's for years. She was dying to meet her."

The couple took four-month-old daughter Esmeralda along with them for the lunch, and the celebrity foursome was joined by the Jolie-Pitt clan of kids, including Shiloh, Maddox, Pax, Zahara, Knox and Vivienne.

"They relaxed for a few hours while the kids played," the source said.

The news of the couple joining the Jolie-Pitts for lunch comes one week after reports surfaced which claimed that the couple was once again at the risk of ending their relationship after Mendes reportedly wasn't reacting well to Post-Partum Depression.

"It seems like she's suffering from the baby blues," sources said at the time. "She's been having severe mood swings, making it unbearable for anyone to be around her. One minute she's sending Ryan videos of their daughter, and the next she won't accept his calls."

The couple was rumored to be arguing a lot as a result, though Gosling was trying to get Mendes help before considering ending the relationship.

"Ryan wants to make things better and even suggested they go see someone for help," the source said. "But Eva won't go. She doesn't think there's a problem."
