This is a war of the divas. What, wait? Heidi Montag isn't a diva. She might wish she were, but in spite of Spencer's whining, she's not there yet. Now, Posh, on the other hand is a diva in every sense of the word. But no matter what we classify them as, they both have clothing lines and they're duking it out.

It's Heidi's cheap Anchor Blue junk, versus Victoria's expensive dVb junk. And apparently the junk is flying off the shelves for both ladies.

Heidiwood is sold out at Kitson, on Robertson Blvd. Posh, on the other hand, is seeing hard times. The dVb jeans have been relegated to the sale rack at Loehmann's. Although, the line has completely sold out in Reseda California, but nobody knows where that is anyways -- except the karate kid.

But they're saying that Heidi is outselling Posh. Although we find that hard to believe, as TMZ points out, "It's a lot easier to sell crappy $44.95 jeans, than crappy $250 ones!"
