"That (the item song) was a very fun experience. It's not as easy as it looks and it takes a lot of hard work to look as glamorous. It's not what I thought it would be," the 33-year-old said on Friday at the unveiling of the cover of a magazine featuring her.
"As much as I enjoy watching item numbers, when you are actually doing it, it's much more harder. But a good experience," she added.
'Dhating naach' is the item number which features Nargis in the same frame as Shahid.
Directed by Rajkumar Santoshi, 'Phata Poster Nikhla Hero' also stars Ileana D'Cruz. It releases on August 23.
