Inside the super popular modeling competition!

Things are getting catty on the catwalks, creator TYRA BANKS tells us, as a whole new crop of runway wannabes compete on Cycle 10 of "America's Next Top Model," premiering on Wednesday, Feb. 20th.

"There are four or five girls in Cycle 10 that are like, 'Grrr!'" Tyra reveals. "There's a lot of girls we found that went, 'I don't like her, I don't like her, I don't like her, I don't like her!'"

So what else is new on the hit reality series? Supermodel PAULINA PORIZKOVA, formerly seen on "Dancing with the Stars," joins Tyra on the judging panel. This year's coveted grand prize includes: a Seventeen magazine cover and six-page spread, representation by Elite Model Management, and a $100,000 CoverGirl contract.

The new season kicks off at 8 p.m. Wednesday, Feb. 20th, on The CW, but we have your sneek peek tonight on ET.
