London, March 02: Pop singer Michael Jackson has proved to be a truly loving father, for he has furtively recorded over 100 songs as a legacy for his three children.

The talented `Heal the World' hitmaker will leave the concealed songs as a legacy for Prince, 11, Paris Katherine, 10, and five-year-old Prince Michael II aka Blanket, revealed his biographer Ian Halperin.

"I was astonished by the number of songs, which have been held back. I was told that he will not let them come out now but wants to leave them for his kids, a very personal legacy to them," the Daily Express quoted Ian as saying.

Ian, who has spent five years penning a biography on Michael called `Unmasked-The Michael Jackson Story', revealed that the entertainer was in talks to perform for 30 nights at London's O2 Arena for a whopping 50 million pounds.

"The concert would be his first in years and is being seen as a test to see if he could perform in London but a lot depends on his health," Halperin said.

Meanwhile, `Unmasked-The Michael Jackson Story' will be released this summer. (ANI)
