Kanye West is back on Twitter after taking a long hiatus from the micro-blogging site. Instead of ranting like he usually did before, the rap mogul raised curiosity as he tweeted a mystery "June Eighteen" message. No other explanation was provided.

Given that his girlfriend Kim Kardashian is heavily pregnant, Kanye's cryptic message is suggested as a hint at her due date. Others, however, speculate it as a release/start date of his new work as an artist, possibly his much-awaited studio installment.

Kanye does have an album in the works. It's a long-gestating project with his G.O.O.D Music artists like John Legend, Big Sean and Pusha T with guest appearances from Jadakiss, The-Dream and R. Kelly among others.

He was recently spotted vacationing in Paris with his very-pregnant baby mama.
