Even though this singer isn't 25 anymore, she will forever remember that birthday since she has the numerals tattooed on her forearm. Do you think you can figure out who she is?

This pop-rock chick is pretty bada---, so it's not really a surprise that she's got some ink etched into her skin. Outside of these tattoos, she has several others, including a hand-drawn star to celebrate her breakthrough album as well as her famous reality TV BF's name on her ribs. But this Canadian songstress also has a tattoo of her ex-hubby's initials, which is a bit awkward, although it doesn't seem to bother her in the slightest since they remain friends.
