Should I tell a friend that her tattoo is misspelled?

A friend of mine from High School(which is 10 years past) recently posted a picture to Facebook of her tattoo, it's of the lyrics to a song the chorus of which includes the word "Breathe" but instead it says "Breath". There isn't enough room to put in the second 'e's without making the tattoo look very messy. She plans to get the rest of the song tattooed on, should I point out the mistake now so that they can put in the right spelling or would I look like a big jerk?

Like I said she's a friend of mine from High School and we were really close at the time, but now we're not as close and haven't seen each other for a while. Should I point out the mistake? I'd send it as a private message so that others wouldn't see it, but it could still be humiliating I'm afraid, or I'm worried that she'd take offense that I was pointing out a spelling mistake and not saying how good the tattoo looks. And for the record it looks great, but the misspellings kind of jump out when I see it.

So: Should I tell her that her tattoo is misspelled? Any serious answers would be greatly appreciated.
