13 Hearts but Nothing else

What has 13 hearts, but no other organs?
There is a very simple answer which you will be kicking yourself over after you see it. There is only one possible answer...

• Someone told me this riddle two weeks ago (to which I guessed the answer correctly). But the point is, that means you might have not come up with the riddle yourself. If that is the case, please include where or how you found the riddle. – Mr Pie Aug 5 '18 at 9:14
• Since @user477343's answer was considered the correct one (at least among some religious community), and since F1Krazy's answer seems definitely valid, there is apparently not "one possible answer". – xhienne Aug 5 '18 at 10:32
• A third possible answer is "this shirt I'm currently wearing" ;) – jafe Aug 5 '18 at 11:26
• @jafe Hahahah :D – Mr Pie Aug 5 '18 at 22:52
• Another alternative answer: My freezer. Please don't call the cops. – Ontamu Aug 6 '18 at 6:18
