Hayden and Kristin's Retail Romp

"Heroes" star Hayden Panettiere is dating Kristin Cavallari's "Laguna Beach" ex, Stephen Coletti. This made it just a tad awkward -- when the two underage beauties just so happened to run into each other at an L.A. shop! Meow!

The rival sex kittens kept their claws in check as they joked, laughed and browsed the aisles of trendy Surly Girl boutique, located on L.A.'s starlet row, aka Robertson Blvd. Someone, alert the media!

With their purchases in hand, the blonde bombshells bid their adieus and went on their separate ways. Until they meet again... at Hyde!
