Kristin Cavallari Just Came Face To Face With This Former 'Hills' Frenemy

Who did the shoe designer run into on the red carpet in NYC?

Though Kristin Cavallari and Audrina Patridge famously competed for the affections of Justin Bobby Brescia on "The Hills," those hard feelings are clearly history -- and the rest is still unwritten.

Soon-to-be mother of three Kristin, who was hosting Chinese Laundry's annual presentation in NYC, posed for pics with her fellow MTV alum before they hit up the VIP section to chat privately. And no, she didn't declare, "It's f**king on, bitch!"

“I haven't seen Audrina in awhile, and I'm so happy that we were both in New York at the same time,” the shoe designer told US Weekly. “I love her to death. I'm so thankful and happy that she came. She looks amazing, and it was really fun to catch up with her.” Bye bye, Tinseltown drama!
