In a subsequent photo, Bloom poses proudly with his tattoo artist, Balazs Bercsenyi.

The tattoo features a series of numbers and Morse code between two thin black lines. After fielding some incorrect guesses, the 43-year-old later replied to a fan "It’s Flynn in MORSE CODE and his dob and time."

Unfortunately, the sweet gesture was quickly overshadowed by the fact that the tattoo spelled out "Frynn" instead of "Flynn" in Morse code.

However, his tattoo artist made sure fans knew that he could fix it. On Bercsenyi's personal Instagram, the he admitted, "yes, a dot is missing, we know, it will be fixed" along with a smile emoji.
