Item-bomb

Implying that Ms. Kaif has, so far, not been appearing as an item in her movies.

Right.

Katrina to play a bit role would be more appropriate, if you ask Pranab Mukherjee. (Hazard Warning: Do NOT ask Mahesh Bhatt!!!)

Please also note that according to the report, Kat would not play the role (as opposed to a hole) of "an" item girl, but the generic idea of "item girl" in its entirety. Plato would be proud.
