Hold a slot open in the pantheon of celebrity catfights. There's yet another lady-style brawl brewing as Anna Nicole Smith wags her sausage-like "No you di'int!" finger in the face of Carmen Electra.

Just like TrimSpa's beefy spokesgirl, the former Navarro-jockey has signed on to endorse her own line of weight-loss pills, and the wobbly widow isn't happy.

As Star reports in an issue hitting newsstands tomorrow, the video-diary section of Smith's website (available only to subscribers) currently contains a clip of her mocking Electra as too svelte to hawk diet pills (Electra insists she pops the pills to maintain her weight).

"I don't understand it," Smith blathers. "I do these diet products. I do TrimSpa ... [but] she was never fat ... I swear, it's crazy!"

We're sure that's just the pills talking.
