TMZ first reported the baby's moniker after obtaining the birth certificate, and a source confirmed to E! News as well.
While the good-looking duo has remained mum on their family's new arrival, we have learned that they're over the moon and madly in love with their daughter.
"They're both great, but exhausted," a source told us at the time. "They know it's going to be a little while before the baby adjusts to a schedule."
Of course, they've had some help with the baby around the house as both Gosling's mom, Donna, and Mendes' mother, who's also Eva, have been at the house working on cooking and cleaning for the new family of three.
