Emmy-winning talk show hostess Tyra Banks made Perez Hilton promise to stop writing derogatory stories about underage stars just days before Demi Moore challenged the acid-tongued blogger to a Battle Royal for targeting her 15-year-old daughter Tallulah.

Last week, the Ghost star took Hilton to task on Twitter.com over “pornographic” and “perverted” pictures he posted of her daughter.

In the season premiere of The Tyra Banks Show, recorded August 18, and expected to air Tuesday, Tyra makes Hilton vow to quit picking on young celebrities for six months in exchange for a guest judging role on her runway reality series America’s Next Top Model.

“When you’re a kid, especially the kid of a celebrity, I don’t feel they should be put in the public in a way to be made fun of. I feel they should be protected,” she told him.
