Yesterday was April Fool's Day and a ton of celebrities got in on the joke!

Two of the very best pranks were pulled off by Sharon Osbourne and Snooki.

Sharon Osbourne told the world she was pregnant and a TON of people believed her! Sharon revealed the news on her show 'The Talk', where she said she tried in vitro and IT WORKED! She revealed later on the show that it was all just a joke.

Snooki, however had a slightly more believable story. She said that here and fiancée Jionni had eloped! However, when prodded for photos she posted a really terribly photoshopped one. Joke's over.
