Kim Kardashian and Kris Humphries' wedding guest list is THE list to be on ... and talk show host Ellen DeGeneres wasn't originally invited to Saturday's lavish Montecito ceremony! But a simple Tweet has changed everything.

Ellen wrote:

    “No invitation to Kim Kardashian’s wedding yet. Worst Thing In The World.”

Shortly after the Tweet, the bride-to-be responded, "Of course u are invited!!!! COME!”

Wonder if Ellen's wife Portia can come, too? Oh, the power of Twitter!
