London, July 27 : Some never-seen-before family pictures of Michael Jackson with his kids have been revealed, giving a peek into the hidden world of the Late King of Pop's relationship with his children.

In one photograph, the `Thriller' star's daughter Paris, 4, is seen sitting tenderly on her dad''s knee at her elder brother Prince''s fifth birthday bash in April 2002.

Another picture shows blonde-haired Prince as a toddler, wearing a party hat with cake on his face, while Jackson is sitting next to his son, tucking into the dessert.
