The A-list couple have yet to comment on the birth or name of the child, but we will now refer to her as the Most Beautiful Baby Girl In The World.
Eva and Ryan have never publicly commented on the reported pregnancy, but word got out that Mendes was expecting about seven months later.
Back in February, Eva appeared on "The Ellen DeGeneres Show," where she addressed the rumors that she was expecting.
"It all started because I didn't want to go through the scanners at the airport," she said, referring to a pre-flight security check at LAX. "You know, those X-ray scanners, which are really creepy? They basically see you naked. And not only that, but there's a radiation aspect to it. So I always opt out. I always ask for a personal pat-down. That was good enough reason [for people to assume I'm expecting a baby]."
The pair have been dating since the fall of 2011, when they met after co-starring in the drama "The Place Beyond the Pines." This is the first child for both actors.
