TMZ broke the news, reporting that the couple welcomed their second daughter, Amada Lee Gosling, at 8:03 a.m. on Friday, April 29 in Santa Monica, California.
The pair are already the proud parents to their little girl, 20-month-old Esmeralda Amada.
Both of the Gosling girls now have the name Amada in their title, with Eva explaining it has a very sentimental meaning.
โAmada was my grandmotherโs name. It means โbelovedโ in Spanish,โ Eva told The Violet Files in 2014.

Ryan, 35, and his 42-year-old partner first began dating back in 2011, after they met on the set of their film, The Place Beyond the Pines, in which they played parents.
In a case of life imitating art, the genetically blessed duo couldnโt be happier with their growing family unit.
News of their second pregnancy only broke last month with an insider revealing to E! News Eva was in her second trimester.
As for why they kept it under wraps? A pal close to the actress explained to People that she โjust hasnโt ever wanted anyone beyond her close friends and family knowing more than they had to. And Ryan is certainly private and always has been.โ
Last year Ryan spoke to Hello! about fatherhood, admitting he was loving bonding with Esmeralda.
โThis will be our first Christmas where [Esmeralda is] sort of taking it all in, so thatโs exciting,โ he said at the time.

The duo have been together since 2011
Before adding being a dad was โnot rocket science.โ
His love for Eva was just as apparent, with the actor telling the publication: โI know that Iโm with the person Iโm supposed to be with. [The only quality I want is] that sheโs Eva Mendes. Thereโs nothing else Iโm looking for.โ
Congratulations to the happy couple on their new bundle of joy.
