Ryan Gosling and Eva Mendes reportedly welcomed a baby girl on September 12.
This is the first child for 33-year-old Gosling and 40-year-old Mendes. The celeb couple managed to keep the pregnancy undisclosed for seven months.
Mendes even went on The Ellen Show to say she was not pregnant. She told the host Ellen DeGeneres, "It's so ridiculous. It all started because I didn't want to go through the scanners at the airport, you know, those X-ray scanners, which are really creepy -- they basically see you naked, right? And there's a radiation aspect to it, so I always opt out." However, it is now clear she was pregnant then.
The pair has been dating since September 2011, after meeting on the set of The Place Beyond the Pines, in which they starred together.
Earlier Gosling, 33, had said that he would "make movies until he started making babies, "since he wasn't sure if he could manage to be both, a parent and an actor".
