Battle Of The 'Baywatch' Babes: Inside Pamela Anderson's Behind-The-Scenes Rivalry With Co-Star Donna D'Errico

"Pam says all the other girls on the show used to say Donna was the dim one," an insider shared about their behind-the-scenes feud. "When Donna walked by, says Pam, they would joke, 'The village has lost its idiot."

"According to Pam, Donna believes that Mount Rushmore is a natural phenomenon and the effects of the wind and rain carve the faces into the rock," the source alleged.

"Pam also says that Donna gets upset during media interviews because the person asking her questions doesn't want to know about Donna — just about what Pam was like on Baywatch."

As for D'Errico, she reportedly questioned Anderson's acting abilities.

"Normally I would say she has no talent," D'Errico allegedly jabbed. "But after seeing her cry over Tommy Lee on Jay Leno's Tonight Show, I'd say they gave the Oscar to the wrong chick."

Pals don't believe the queens of the beach are done squabbling.

"This is all building up to a real battle of the Baywatch babes," said the insider, warning, "If they're ever face to face again, they'll scratch each other's eyes out."

Pamela appears to have had the last laugh, slamming critics and taking control of the narrative by exposing the highs and lows of her career and private life in her own words.
