Before Padma Lakshmi came aboard, Billy Joel's then-wife Katie Lee served as host of "Top Chef" on Bravo. The first time they shot the portion in which one of the competitors would be sent home, Cohen and the rest of the crew began hearing a strange thumping noise coming over the sound. "Nobody could figure out what it was," Cohen wrote. "Was someone pounding on a door somewhere? Was a piece of equipment failing? Finally the audio guy realized what he was hearing. 'That's Katie's heart!' he screamed. I love a host with a big heart, and Katie Lee felt so bad about having to send anyone home that hers was pounding hard enough to be heard in the sound mix."
