If ya think there's a blonde-on-blonde battle brewing between Pamela Anderson and Jessica Simpson, think again.

Reports that Anderson has lashed out against Simpson for wearing a T-shirt recently that read "Real Girls Eat Meat" have been greatly exaggerated...

Yes, the former Baywatch babe called Simpson a "bitch" and a "whore" during an Australian radio show, but her tone was way more cracking a funny than battle cry.

The star of E!'s new reality series Pam: Girl On the Loose laughed when one of the radio hosts, Jackie O, asked her about the T-shirt and explained, "This is the first time I've heard about it."

When the other host, Kyle, suggested that Simpson's tee was more adult than animal themed, Anderson cracked. "She was not referring to actual, you know, cows and chickens. I think she was referring to men."

Meanwhile, I hear Anderson is driving to Las Vegas this weekend to celebrate her birthday (she turns 41 tomorrow). The roadtrip will apparently include a stop at the world's largest thermometer (it's 134 feet tall) in scorching hot desert town Baker, Calif., to cook veggie burgers on the pavement.

Yummy.
