The 46-year-old fashion icon said although she loved giving lifestyle advice to young women, she often got nervous, reported Elle magazine.
"I don't think (I'd ever do a reality show again). I loved my girls (from The Face) and I loved teaching them. I got a little bit nervous - I didn't like when it came to PR time. Reality (TV), for me, is a very fine line," said Naomi.
The British model also said she was all natural on the sets of the show and felt proud, protective towards her contestants.
