Watch out, she's got a bat!

NAOMI CAMPBELL was a good sport on last night's "Ugly Betty," which poked fun at her famous temper and cell-phone-throwing history! Dressed in an Elle magazine jersey and high-heeled sneakers, the catwalker faced off against pitcher Wilhelmina Slater (VANESSA WILLIAMS) in a corporate softball game between Elle and the Mode magazine staffs.

When Naomi's phone rang at bat, the entire sports-watching crowd ducked as she whipped it out, and shouted into the receiver: "BONO!? Not now, darling, I'm playing cricket!"

Can't get enough Naomi? Now, you can own the autographed uniform worn by the model herself in a new online auction, which runs until 9 a.m. EST on Monday, May 26, and benefits Clothes Off Our Backs, an organization that raises money for children's charities.
