Aniston was first spotted with the tattoo in 2018, and a source tells People that the "very spiritual" star finds the numbers to be good luck.
“The number 11 is also special to her because of her birthday and Norman,” the source says. Aniston's Welsh Corgie-Terrier named Norman died in 2011, and her birthday is on Feb. 11.
The possible reason behind the wrist tattoo holds up as Aniston also has "Norman" inked on her right foot in honor of her late pet.
Meanwhile, Aniston's ex-husbands, Brad Pitt and Justin Theroux, have numerous tattoos all over their bodies. Like the actress, Theroux also has two tattoos dedicated to his dogs that have died, which are prominently located on his back.
