The impossibly attractive actors, who began dating three years ago, have given the baby daughter they welcomed Sept. 12 in L.A. the exotic moniker of Esmeralda Amada Gosling, according to the birth certificate obtained by The Insider With Yahoo.
Baby Name Wizard website reports that Esmeralda is "a borrowing of the Spanish name Esmeralda, which is taken from the word meaning 'emerald.'"
It's also the name of the character Mendes played in a 1999 episode of the Pamela Anderson TV series V.I.P. early in her career.
The new addition also shares her name with a character from the 1831 Victor Hugo novel, The Hunchback of Notre Dame, and the 1996 Disney version.
Esmeralda is the Gypsy woman beloved by Quasimodo. However, she isn't likely to find any pre-made merchandise, such as notepads or license plates, with her name on it.
The name peaked in popularity in the U.S. in 2007, according to the website, and in 2012, it ranked as the 358th most popular name given to baby girls.
Baby Gosling's middle name, Amada, is the name of Mendes's character in the 2007 crime drama We Own the Night, who's the girlfriend of Joaquin Phoenix.
The star spoke about the importance of that film when she was asked whether it was "a big deal" for her during an interview.
"It's a huge deal for me. Huge!" Mendes told Australian website Femail in May 2007.
"I've never worked at this level before. Even though I've worked with amazing people, I've never worked on something like this. I did a drama once. The first kind of thing that broke me out was 'Training Day,' but I only had two scenes in that. Not to minimize that but it was on so much of a lesser scale. The movie wasn't but my scenes were. I barely spoke in that one, even though it got me a lot of attention. I've never been pushed and challenged like this on a daily basis before."
