Couples who ink together, stay together .... right? Our spies have noticed that Avril Lavigne and boyfriend Brody Jenner have permanently professed their love for each other with tattoos. Doesn't this seem a bit premature considering they've only been an item for less than four months?

If you look closely in our exclusive photos of the couple enjoying a day at the beach, you can clearly see Avril's "Brody" tattoo next to her right breast. As for Brody's "Avril" tattoo, it's on his inner arm.

Something tells us that this relationship won't outlast the ink.
