It's Miley Cyrus' tattoo!

The 'We Can't Stop' songstress and her boo Liam Hemsworth have matching Mexican sugar skulls on their feet, but these aren't symbols of Miley's burgeoning rebelliousness -- these have a deeper meaning.

Now, let's just hope Miley and Liam make those "to death do us part" vows and then they won't totally regret their matching ink!
