TMZ.com caught Laguna Beach’s Stephen Colletti (who is 21) and “Heroes” Hayden Panettiere (who is 17) sharing a snack and a kiss in Hollywood. Could their romance be blossoming after the so-called fighting with Stephen’s ex, Kristin Cavallari?

TMZ.com reports “”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!”
