Ryan Gosling and Eva Mendes Welcome a Baby Girl

Cue the "hey girl" puns.

Eva Mendes gave birth to a baby girl on Friday, September 12, Yahoo can confirm. This is the first child for the actress, 40, and boyfriend of three years, Ryan Gosling, 33.

Rumors first swirled that Mendes was expecting in February when she supposedly told TSA officials at Los Angeles International Airport that she didn’t want to go to through the body scan at security because she was pregnant.

"It's so ridiculous," she later said, slamming those reports on The Ellen DeGeneres Show. "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 not only that, but there's a radiation aspect to it, so I always opt out."

Mendes kept an extremely low profile in the months that followed, so low, that many speculated she and Gosling were over. The actress didn't even make an appearance at the Cannes Film Festival in May for his directorial debut of Lost River, which she stars in as well.

By July, her absence was explained. It was confirmed that Eva and Ryan were expecting their first child together and that she was already about seven months along. However, the couple never addressed the pregnancy news.

Mendes and Gosling began dating in fall 2011 after meeting on the set of The Place Beyond the Pines.

"I'd like to be making babies but I'm not, so I'm making movies," Gosling told U.K.'s The Times that same year. "When someone comes along I don't think I'll be able to do both and I'm fine with that. I'll make movies until I make babies. I have no idea when the handover will happen.”

Here's hoping Gosling masters the art of multitasking.
