Bloom's tattoo artist acknowledged the mistake on his Instagram. "A beautiful reminder for @orlandobloom of his son ?? and yes, a dot is missing, we know, it will be fixed :)," he wrote alongside a close-up of the ink.
The actor welcomed Flynn with his ex-wife, Miranda Kerr, in 2011, and plans to expand his brood with fiancee Katy Perry.
"We are shooting for [having kids together]," Bloom revealed on The Howard Stern Show last year. "It's like this wild mustang. If we can just wrangle this beast and get on it, we’ll have the ride of our life."
