Gibson's kids to hire lawyers over Oksana Grigorieva pregnancy rumours

Melbourne, May 11 (ANI): Hollywood actor Mel Gibson's adult kids are, reportedly, planning to hire lawyers to protect their inheritance after knowing that his Russian girlfriend Oksana Grigorieva is pregnant.

According to the National Inquirer, Gibson's twins Edward and Christian, 26, are seeking legal help after he apparently told his seven offspring that he and his new love were expecting a child.

"In late April, Mel gathered his children at the family home in Malibu and broke the news that Oksana is pregnant, and he expects them to accept the baby as a new sibling," News.com.au quoted a friend of the actor as saying.

"They are quite upset," a source said.

"Even though Mel assured them the pregnancy was unplanned, they're furious with him and say they're going to take steps to protect their inheritance, which they feel is in jeopardy," the source added.

Meanwhile, Grigorieva is said to have installed private security guards outside her Los Angeles home as Gibson's divorce battle gears up.

Two men in a dark car have been guarding Grigorieva's home in Los Angeles in recent days. (ANI)
