The Sun reported Omer was sitting a few rows back at the memorial service for Michael July 7 before Jacko's sister Rebbie moved him to the front row alongside MJ's mother Katherine Jackson, and his three children Prince, Paris and Blanket.

Omer has since been staying at the Jacksons' home in Los Angeles and is believed to be seeking a DNA test, the newspaper said.

'If Omer's his son, he's his son,' Michael's brother Jermaine Jackson told the Daily Mail.

'We won't deny it. We are going to give him the same love and care that we give Prince and Paris and Blanket. I can't clearly say if he is Michael's, but I saw this kid around him.'

Meanwhile, it has been announced that Michael's mother Katherine, 79, will share custody of the three children with Debbie Rowe, the biological mother of Prince and Paris.
