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...

However, he's not the only famous face to receive a truly effed up gift. From body parts to actual bodies, check out six other crazy gifts that celebs have received!

In the wonderful world of music, collaborations happen all the time – practically on a daily basis. But in some cases, you never would have thought to put the two artists together. And that's when the magic happens.

Adam Levine and Glee’s Matthew Morrison are teaming up to cover Frank Sinatra’s “Luck Be a Lady” for Matthew’s upcoming album, which is under Adam’s label 222 Records. Kind of a random combination, right?

If you're upset about "Die Young" being played on the radio, don't blame Ke$ha. She didn't even want to sing it!

At least, that's what she's claiming now. Her latest single, which reached as high as No. 3 on the Billboard Hot 100, has nothing to do with violence or guns, but it's still a sensitive spot after the tragedy at Sandy Hook Elementary last week. Numerous radio stations have since pulled the song, and amidst the backlash, Ke$ha now says she was forced to sing the song. "I had my very own issue with 'Die Young' for this reason," she tweeted last night. "I did NOT want to sing those lyrics and was FORCED to."

What else did Kesha have to say? Find out after the jump!
