Michael Jackson's secret son?

A boy brought up by legendary pop star Michael Jackson and his family is rumoured to be his secret son, according to insiders.

Donte Williams Jackson may be the son of the King of Pop and a mystery woman he had a brief fling with.

The Jackson family has raised the 18-year-old boy since he was a toddler and he still lives with Jackson's 80-year-old mother Katherine.

Alejandra Oaziaza, who has four kids by Jacko's brothers Randy and Jermaine, mainly looked after Donte.

Earlier, it was thought that Donte was the son of Alejandra and Randy, before she left him for Jermaine.

But he can't be their biological son as he was born just eight months after their previous child.

It is now being speculated that Donte is the son of Jackson from an affair in Las Vegas in the 1990s.

"Michael was always very close to Donte. We're not even sure if Donte knows who his parents are. He's one of the nicest kids you could possibly meet," The Sun quoted a source as saying.
