Piers Morgan reveals star secrets in new book

Piers Morgan has revealed secrets of many Hollywood celebs in his latest book 'Shooting Straight

Morgan said that he drove over to Mel Gibson's house in Malibu to try and persuade him to do an interview, and Gibson detailed the extraordinary pain and bitterness he felt towards his former lover Oksana Grigorieva, the Mirror reported.

The 48-year-old journalist said that the 'Braveheart' star was not up for an interview, as he didn't trust himself to not explode and say things he would regret later.

Morgan has also insisted that his interview with Janet Jackson was a fascinating insight into the weird, fantastical world of the world's most famous showbiz family.

He had asked her what she used to call her famously dictatorial father, Joe Jackson, to which the 47-year-old singer said that she referred to him as Joseph.

The 'Together' Again' hitmaker also said in her interview to Morgan that she had once tried to call him dad, but he was pretty strict about her calling him Joseph.

Jackson also had revealed to Morgan how some female stars eat Kleenex tissue paper to clog up their stomachs so they don't feel hungry, among other worse stuff.

Morgan had earlier revealed that Charlie Sheen had once invited him to get hammered.
