When most fans want to give their favorite celebrity a little something, they make a card or leave a nice tweet.

Then there are the more... devoted fans. 30 Seconds to Mars frontman Jared Leto revealed during a recent radio interview that a fan mailed him an actual human ear! "Someone cut their ear off once and sent it to me, that was very strange. A whole ear. The Van Gogh move," he said. "The note just said, 'Are you listening?' I never knew who it was, who's missing their ear out there." No word on what Jared did with the ear, either...

It shouldn't have been necessary for an animal to die in order for Taylor to get a gift but, well, that's not what one fan thought. They sent the singer a turtle shell with her portrait on it.

2. One Direction

1D member Louis Tomlinson once received a live hermit crab from an admirer, but Harry Styles has him beat in the bizarre gift department. He recently claimed that a fan went to his hotel room and pushed a sanitary napkin with her number on it under the door. Harry never told what he did with the napkin, but we're assuming he didn't place it next to his many awards.

3. Ke$ha

Most celebrities would try to avoid getting body parts from fans, but she actually requested them. After a plea for human teeth, her fans delivered by sending more than 1,000 of the little guys and she used them to make a bra, headdress and jewelry. It's probably a good thing she didn't ask for anything more extreme than that!

4. Jonas Brothers

Baby sharks can be kind of cute, but only in movies and at a safe distance. The Jonas Brothers received a baby shark from a fan that was dead and preserved in a tube.

5. Avril Lavigne

When Avril Lavigne opened up her fan mail a couple of years ago while in Japan, there were some cards, a few autograph requests... and a dead rabbit.

6. Dolly Parton

The crazy country singer fittingly received the craziest fan gift of all time when a newborn baby named Jolene was placed on her doorstep! There wasn't too much bonding time that followed afterwards because Dolly immediately called Human Services.

What do you think was the worst fan gift?
