London, July 21 - Michael Jackson's six-year-old son Blanket is still unsure of what has happened to his father and asks whether he has gone on holiday, says Mark Lester, godfather to the late pop star's children.

Jackson, who died June 25, has three children -- 12-year-old Michael Jr, 11-year-old Paris Michael Katherine and six-year-old Prince Michael II whom Jacko called Blanket.

According to Lester: 'It is obvious to me that Blanket is still unsure about what exactly happened to his father. He said, 'Where's Daddy gone? On holiday?' It was a rhetorical question and it broke my heart.'

'Prince was taciturn, unusual for him, but we still had a hug,' mirror.co.uk quoted Lester as saying.

'Paris gave me a tight hug and we just held each other for a while. We were both welling up. I told her that her dad would always lie in her heart and be remembered by at least half of the world. Paris replied: 'I'm just glad he is at peace',' he added
