And like many others who follow this particular trend, her Hebrew tattoo is a bad one.
Christina was going for the initials of her husband, Jordan Bratman, so her tattoo is supposed to say JB. Unfortunately, when you look at it, you just see the number 12 (like in 12th grade), as that's what this letter combination means in Hebrew.
See, biblical Hebrew doesn't have the letter J, and whoever advised Christina was probably unaware of the modern alternative, and used the letter Yod instead. You don't need to be a Hebrew linguist to realize that a letter named Yod doesn't sound much like the J in Jordan.
The second, and bigger, problem is that in Hebrew you don't just write initials as a bunch of letters. For Hebrew initials and acronyms you use a special punctuation mark called Gershayim (and looks like double quotes), before the last letter. When writing foreign initials, you just spell out the letters fully.
As for JB, the best way is definitely to spell it out (Jay.Bee), using the modern spelling of J (Gimel with Geresh). This is what Christina Aguilera should have gotten:
