London, Apr 23 : Hollywood actor Mel Gibson's lawyers have silenced Russian pop star Oksana Pochepa from speaking out about their relationship until divorce settlement.

The 24-year-old singer said they feared an affair could cost the actor a fortune in his 640-million pound divorce.

However, she refused to deny a relationship with the Braveheart star, or pregnancy rumours.

"Until Mel and his wife Robyn settle their relations, no one has the right to speak about this," the Sun quoted Pochepa as saying.

"It is unfair. It's not normal. As soon as the divorce happens, I will be able to comment.

"He is a superb man. I have no choice except to keep silent now," she added. (ANI)
