It is good to be under-prepared for live TV: Guiliana Rancic

TV anchor Giuliana Rancic says being a "little less prepared" for a live event enhances her performance.

The 40-year-old E! presenter is always handed detailed notes when she is due to work at red carpet events, but would rather not do too much research so that she can notice the smallest details, which otherwise go unseen, reported Glamour magazine.

"E! gives me and my co-host, Ryan Seacrest, these binders with research and prepared questions; Ryan reads it all but I'm more relaxed.

"I like to be a little less prepared, because then I notice little things - like Amal Clooney is wearing gloves that maybe don't fit perfectly. I wouldn't notice these details if I was fixating on my notecards. Basically the more under-prepared I am, the better," she said.
