Pamela Anderson may want to set a little extra cash aside for the future therapy bills of sons Brandon, 10, and Dylan, 9, now that she's clued them in to some very personal facts of life.

The top-heavy blond, 39, tells the London Sun how the three of them watched the brilliant cringe-fest that is "Borat," in which the sex tape she made with their dad, Tommy Lee, plays a prominent role.

"They really wanted to see [it] and I finally had a breakdown and let them because all their friends had," she explains, "and I said, 'There are a few things we have to talk about before you see 'Borat.'"

Brandon and Dylan chimed in that they already knew "about the magazines," an apparent reference to her many Playboy spreads, so at that point, recalls Anderson, she sat down and watched the flick with them.

According to Pam, "I kind of went 'la la la la la la la' over the parts I didn't want them to hear," specifically, the graphic testament of her once deep, deep affection for their father.

"I said, 'You know, when your dad and I were first together we used to videotape everything,'" shares the amiable actress. "Everybody's naked, hugging, kissing, all that good stuff and someone stole the tape."

That apparently got Dylan thinking, because a little later Pam says he asked, "You mean everybody has seen this?"

And in an answer that will likely be replayed again and again on their therapist's couch, their mom came clean and informed them, "Yes."

"Borat" aside, Anderson insists her boys don't know her as a cartoonishly proportioned bombshell. Instead, "They know I'm at school with the neon vest parking cars and doing safety patrol."

That is, when she's not being jetted to England for obscenely extravagant soirees tossed by impossibly rich royalty.

The London Daily Mirror says Pam will be one of the guests at a weekend birthday bash hosted by Prince Azim, whose father is the Sultan of Brunei, a man so rich he could buy a small country with the money fished out between the cushions of his private plane.

The prince, who is turning 25, will reportedly shell out $14 million for the event at his sprawling estate, including $10 million just to have Michael Jackson show up and scare hobnob with the crowd.

"Absolutely no expense is being spared for his party," a mole tattles to the tab. "Michael Jackson is his all-time idol and he said he'd pay whatever it took to get him over. Even though Michael won't be performing, the very fact that he'll be in this stately home mingling with all of the prince's pals makes it worth every penny to Azim."

The eclectic guest list is also said to include Kate Moss, Naomi Campbell, Faye Dunaway, Olivia Newton-John and Dionne Warwick, who will purportedly pocket $500,000 to sing a few ditties.

In addition to plenty of standard extravagances such as champagne, foie gras and caviar, Azim's celebrity well-wishers will also be treated to gift baskets brimming with high-end goodies, including diamond jewelry, iPods and ridiculously expensive Crème de la Mer face cream, according to the paper.

"Prince Azim wants his bash to be more glamorous than the Oscars," says the source. "He's adamant it should be talked about for years to come."
