London, Apr 21 : Russian popstar Oksana Pochepa, who claims to be Mel Gibson's lover, maintains a sex diary to record how often she has slept with guys.

The 24-year-old beauty even rates all her men as to how well they satisfied her.

"She once showed me the diary and I could barely believe it," the Sun quoted a pal as saying.

"Sex is the main thing for her," the pal added.

Pochepa says she is smitten by the 53-year-old actor and hopes their love is "strong and long-lasting".

Just weeks after the snaps were published, the movie legend's wife Robyn Gibson, 52, filed for divorce.

"This is serious and I hope that our union will be real and strong and long-lasting," said Pochepa.

"We are different people, but Mel is a grown man and knows precisely what he wants and me too - I know what I want," she added. (ANI)
