Celebrity singer Michael Jackson once again grab the eyes of the outer world, shopping out in a wheelchair wearing pyjamas.

He was spotted and photographed at a book and toy shop in Las Vegas, near his home. Jackson's bizarre appearance sparked fears on his health.

Jackson, who was disguised with dark glasses and a surgical mask, spent about two hours inside the Barnes and Noble store.

Reports say that the pop star was accompanied by his children, Prince Michael 11, Paris ten, and six year old Prince Michael II.

There are reasonable base to argue on his health as the singer no more is the young dynamic guy as shown in his albums, he turns 50 next month.

One among the eight security guards pushed Jackson's wheelchair around the shop. Onlookers were surprised to see their celebrity singer in such a helpless condition.

Even though unhealthy and amidst controversies, Jackson, to reconfirm the world that still he remains the King of Pop music, a new double album, named King Of Pop, is set to be released to mark his 50th birthday on August 29.
