Ryan Gosling is once again proving that he not only loves his baby girl Esmeralda, but that he may just be one of the coolest dads ever.

Break-Up Rumors Resurface After Ryan Gosling & Eva Mendes Are Spotted In Different Cities

The The Nice Guys actor was spotted out in Los Angeles on Friday with what appeared to be a new tattoo on his knuckles, one which honored his daughter with girlfriend Eva Mendes, Esmeralda Amada.

While it is still unclear whether or not the tattoo is permanent or was a temporary addition to the actor's look, he appeared to have the letters ESME written across the fingers of his left hand-a touching tribute to his daughter, who was born in September.

Are Ryan Gosling & Eva Mendes Prepping For Baby Number 2?

Gosling and Mendes managed to keep the news that they were expecting a child together a secret for most of the pregnancy, with news only breaking in July 2013 that a baby was on the way for them.

And while the recent move to potentially keep an abbreviated version of his daughter's name on his hand wherever he goes is adorable, he isn't the only celebrity who has honored his child in such a way.

Kanye West debuted a tattoo honoring both his mother and his daughter with wife, Kim Kardashian, a few days prior to Gosling, in a photo on Kardashian's Instagram page, which shows the rapper's wrists featuring both dates in roman numerals.

Actress Angeline Jolie also has ink devoted to her children on her body, with the coordinates of each child's birthplace tattooed on her arm, a move she made after rehabbing her image following her divorce from Billy Bob Thornton in 2003.

Other celebs who have made less permanent changes to their body but who still honor their children in special ways, including nameplate necklaces, include moms Kate Middleton, Kardashian, Vanessa Minnillo, Adele and Beyonce.
