"He was such a good friend," Seacrest tells E! News' Giuliana Rancic today. "He was a teacher to me and I felt like a student. I was always in awe of him, just wanted to please him every time I got a chance to work with him."
Seacrest recalled being "so scared" when Clark invited him to cohost New Year's Rockin' Eve with him in 2005, a year after Clark suffered a stroke and missed his only countdown in 32 years.
