What's the significance of the date? No one knows. But, given the fact that West and girlfriend Kim Kardashian are expecting their first child sometime this summer, there's a good chance it could be Kardashian's due date.

If that's true, their baby would be a Gemini like West, whose birthday is June 8.

What do Kim Kardashian and Kanye West want to name their baby?

If it's not the due date, perhaps Kanye fans can expect some new material on June 18.

What do you think the date signifies, if anything?
