Multiple sources have told Us magazine that a super-cute little bundle of girlie joy arrived on Friday 12 September.
Rumours started doing the rounds that 40-year-old Eva and Ryan, 33, were expecting their first baby back in July, when she was already seven months pregnant!
Eva and Ryan started dating in 2011 after meeting on the set of The Place Beyond The Pines, in which they both star.
Speaking to Stylist magazine in 2011 about motherhood and how her role as a mum in her film See If I Care made her think differently about it, she said she wasn’t in a rush to become a mother.
"In a weird way I fluctuate between not giving it any thought and wanting to leave it up to whoever’s running the show, then giving it a lot of thought. I have to be honest, I don’t feel the urge yet.
"Maybe I’ll do it when I’m 41 or something; that’s happened to a lot of people I know who decided not to. I don’t feel the ticking clock… I feel I have time. Whether that’s a reality or not, I don’t know. I’ll just be patient."
So congratulations to Eva and Ryan for having (we assume) the most beautiful baby ever born!
