Eva Mendes, Ryan Gosling

Ryan Gosling and Eva Mendes have welcomed what we can only assume is the world's most beautiful baby. According to Us Weekly, Mendes gave birth to a baby girl on Friday.

News of Mendes' pregnancy broke in July, when the actress was reportedly already seven months along.

Gosling, 33, and Mendes, 40, began dating after meeting on the set of A Place Beyond the Pines in 2011. This is the first child for both of them.
