Who said that men can't multitask? Well, they were wrong, obviously - but Kanye West isn't doing a whole lot to repudiate that old cliche.

The rapper, who became a father for the second time recently, took to Twitter yesterday in a rare burst of activity - but he wasn't just hanging out for the sake of it. Instead, he warned people to stop asking him for things until his new album is finished.

He used all caps, too, so you know he meant business.
